A. UTILITY CONSTRUCTION
1.
Public utility installations and structures shall be understood to include all poles,
tracks, pipes, wires, conduits, house service connections, vaults, manholes and all
other appurtenances and facilities pertaining thereto, whether owned or controlled by
governmental bodies or privately owned by individuals, firms or corporations, used
to serve the public with transportation, traffic control, gas, electricity, telephone,
sewerage, drainage or water. Other public or private property, which may be affected
by the Work, shall be deemed included hereunder.
2.
All open excavations shall be adequately safeguarded by providing temporary
barricades, caution signs, lights and other means to prevent accidents to persons, and
damage to property. The Contractor shall, at his own expense, provide suitable and
safe bridges and other crossings for accommodating travel by pedestrians and
workmen. Bridges provided for access to private property during construction shall
be removed when no longer required.
3.
The length of open trench will be controlled by the particular surrounding conditions,
but shall always be confined to the limits described by the County. If any excavation
becomes a hazard, or if it excessively restricts traffic at any point, the County may
require special construction procedures. As a minimum, the Contractor shall conform
to the following restoration procedures:
a.
Interim Restoration: All excavations shall be backfilled and compacted as
specified by the end of each working day. For excavations within existing
paved areas; limerock base or soil cement base (match existing) shall be
spread and compacted to provide a relatively smooth surface free of loose
aggregate material. At the end of each workweek, the S-I asphaltic surface
course shall be completed and opened to traffic. Contractor shall coordinate
his construction activity including density tests and inspections to allow
sufficient time to achieve this requirement. All driveway cuts shall be
backfilled, compacted, and limerock base spread and compacted immediately
after installation. Contractor shall coordinate with the individual property
owners prior to removing the driveway section. Any utility crossing an
existing roadway, parking lot or other paved area shall be patched by the end
of the working day.
b.
All pipe and fittings shall be neatly stored in a location, which will cause the
least disturbance to the public. All debris shall be removed and properly
disposed of by the end of each working day.
c.
Final Restoration Overlay: After completing all installations, and after testing
of the pipe (but no sooner than 30 days after applying the S-I asphaltic
surface), final restoration shall be performed. In no event shall final
restoration begin after substantial completion. Final restoration shall provide
a S-III asphaltic overlay as specified in an uninterrupted continuous operation
until completion. Any additional restoration required after testing shall be
repaired in a timely manner at no additional cost to the County.
d.
Maintenance of all restored facilities shall be the Contractor’s responsibility.
This maintenance shall be performed on an on-going basis during the course
01001-11
e.
of construction. The Contractor’s Progress Schedule shall reflect the above
restoration requirements.
Additional Restoration for Work in Business or Commercial Districts: The
Contractor shall restore all private property, damaged by construction, to its
original condition. Access to businesses located adjacent to the project site
must be maintained at all times. Contractor may prearrange the closing of
business accesses with the business owner. Such prearranged access closing
shall not exceed two (2) hours. Property drainage and grading shall be
restored within 24 hours of backfilling trench.
B. EXISTING UTILITIES
1.
The locations of all existing underground piping, structures and utilities have been
taken from information received from the respective owner. The locations are shown
without express or implied representation, assurance, or guarantee that they are
complete or correct or that they represent a true picture of underground piping,
conduit and cables to be encountered.
2.
The Contractor shall, at all times in performance of the Work, employ acceptable
methods and exercise reasonable care and skill so as to avoid unnecessary delay,
injury, damage or destruction of existing public utility installations and structures;
and shall, at all times in the performance of the Work, avoid unnecessary interference
with, or interruption of, public utility services; and shall cooperate fully with the
owners thereof to that end.
3.
Pipelines shall be located substantially as indicated on the Drawings, but the County
reserves the right to make such modifications in locations as may be found desirable
to avoid interference with existing structures or for other reasons. When the location
of piping is dimensioned on the Drawings, it shall be installed in that location; when
the location of piping is shown on a scaled drawing, without dimensions, the piping
shall be installed in the scaled location unless the County approves an alternate
location for the piping. Where fittings are noted on the Drawings, such notation is for
the Contractor's convenience and does not relieve him from laying and jointing
different or additional items where required. The County/Professional may require
detailed pipe laying drawings and schedules for project control.
4.
The Contractor shall exercise care in any excavation to locate all existing piping and
utilities. All utilities, which do not interfere with the completed Work, shall be
carefully protected against damage. Any existing utilities damaged in any way by the
Contractor shall be restored or replaced by the Contractor at his expense as directed
by the County. Any existing facilities, which require operation to facilitate repairs,
shall be operated only by the owner of the respective utility.
5.
It is the responsibility of the Contractor to ensure that all utility or other poles, the
stability of which may be endangered by the proximity of excavation, be temporarily
stayed and/or shored in position while Work proceeds in the vicinity of the pole and
that the utility or other companies concerned be given reasonable advance notice of
any such excavation by the Contractor.

The Contractor shall give a minimum 5 working day notice prior to utility personnel
interrupting a utility service (water, sewer, etc.) for the purpose of making cut-ins to
the existing lines or for any other purposes, contact the utility owner and make
arrangements for the utility personnel to isolate the existing lines thus providing
interruption which will be satisfactory to the utility owner.
D. EXPLORATORY EXCAVATIONS
1.
Exploratory excavations shall be conducted by the Contractor for the purpose of
locating underground pipelines or structures in advance of the construction. Test pits
shall be excavated in areas of potential conflicts between existing and proposed
facilities and at piping connections to existing facilities a minimum of 48 hours or
1000 feet in advance of Work. If there is a potential conflict, the Contractor is to
notify the County/Professional immediately. Information on the obstruction to be

For ease of calculating pipe deflections in Table 01050-3, begin by providing a unique asset ID
(top of pipe shots and fittings) for each utility and type, numbered sequentially along the pipe
run (including changes in direction) from start to finish of the pipe in the Table 01050-2. Then
branches and services of the same utility type can be numbered. It is recommended that each
utility (water, wastewater or reclaimed water) numbering format be distinguishable from the
other. This will allow organization and convenient sorting after the individual asset table
worksheet tabs are combined in the spreadsheet program prior to copying and pasting to the
deflection table spreadsheet.

SURVEY FIELD WORK
A. Locate, reference, and preserve existing horizontal and vertical control points and property
corners shown on the Drawings prior to starting any construction Work. If the Surveyor
performing the Work discovers any discrepancies that will affect the Project, the Contractor
must immediately report these findings to the County. All survey Work shall meet the
requirements as defined in Florida Administrative Code 61G17-6. Reference and preserve all
survey points during Construction. If survey points are disturbed, it is the responsibility of
the Contractor’s Surveyor to reset the points at the Contractor’s expense. Copies of the
Surveyor's field notes and/or electronic files for point replacement shall be provided to the
County.
1. The Surveyor shall locate all improvements for the project As-Built Asset Attribute Data
using State Plane Coordinates as the horizontal datum and the benchmark referenced on
the Drawings as the vertical datum. The County will provide electronic files of the
Drawings to be used by the Surveyor in complying with these specifications.
2. The construction layout shall be established from the reference points shown or listed on
the Drawings. The accuracy of any method of staking shall be the responsibility of the
Contractor. All construction layout staking shall be done such as to provide for easy
verification of the Work by the County.
B. Only a Surveyor licensed in the State of Florida shall be employed for this Work. All control
points shall be protected by the Contractor from disturbance. If the monuments are disturbed,
any Work that is governed by these monuments shall be held in abeyance until the
monuments are reestablished by the Contractor and approved by the County. The accuracy of
all the Contractor’s stakes, alignments and grades is the responsibility of the Contractor.
However, the County has the discretionary right to check the Contractor’s stakes,
alignments, and grades at any time.
C. Use survey control points to layout such work tasks including but not limited to:
1. Clearing, grubbing, work limits, right-of-way lines and easements
2. Locations for pipelines and all associated structures and appurtenances
01050-8
D. The Surveyor shall reference and replace any project control points, boundary corners,
benchmarks, section corners, and right-of-way monuments that may be lost or destroyed, at
no additional cost to the County. Establish replacement points based on the original survey
control. Copies of all reference field notes and/or electronic files for point replacement shall
be submitted to the County.
3.02
SURVEYING
A. Locate and protect existing horizontal and vertical control points shown on the construction
Drawings prior to starting any work. If the Surveyor performing the Work finds differences
that will effect the Work, the Contractor must immediately report the findings to the County.
Establish control points, lines and levels by instrumentation and similar appropriate means.
The location of these points should minimize the number of sightings necessary to control
the work and the likelihood of the points being disturbed. Preserve and reference all
permanent reference points during Construction. If permanent reference points are disturbed,
it is the responsibility of the Contractor’s Surveyor to reset the points at the Contractor’s
expense. Copies of the Surveyor’s field notes shall be provided to the County.
1. Record locations, with horizontal and vertical data, on project As-Built survey.
2. Make no changes or relocations without prior written notice to the County or without
receipt of written approval from the County.
3. Report to the County when any control point is lost or destroyed or requires relocation
because of necessary changes in grades or locations.
B. Cover for water, reclaimed water and force mains shall vary to provide long uniform gradient
or slope to pipe to minimize air pockets and air release valves. The locations shown on the
Drawings for air and vacuum release valve assemblies are approximate and the Contractor
shall field adjust these locations to locate these valves at the highest point in the pipeline
installed.
C. To insure a uniform gradient for gravity pipe and pressure pipe, all lines shall be installed
using the following control techniques as a minimum:
1. Gravity lines: Continuous control, using laser beam technology,
2. Pressure lines: Control stakes set at 50 ft. intervals using Surveyor’s level instrument.

the Work (or Work remaining) conform to the Contract requirements and the
sequences of Work indicated in or required by the Contract Documents; reflect how
the Contractor anticipates foreseeable events, site conditions and all other general,
local and prevailing conditions that may affect cost, progress, schedule, furnishing
and performance of the Work; and show how the Contractor’s Means and Methods
translate into Activities and logic.
C.
The Progress Schedule will consist of the Initial Submittal, Payment Submittals and
Revision Submittals. Upon acceptance by the County, the Initial submittal will
become the As-Planned Schedule for the Work. Revision submittals upon acceptance
will become the As-Planned Schedule for the Work remaining to be completed as of
the submittal date for that Revision.
D.
References to the Critical Path Method (CPM) are to CPM construction industry
standards that are consistent with the requirements of this Section.
GLOSSARY OF TERMS
A.
The following terms, whether or not already defined elsewhere in the Contract
Documents, have the following intent and meanings within this Section:
1.
Activity Value (Value)  That portion of the Contract Price representing an
appropriate level of payment for the part of the Work designated by the
Activity.
2.
As-Planned Schedule  The first, complete Initial Progress Schedule submitted
by the Contractor with the intent to depict the entire Work as awarded and
accepted by the County or returned as no resubmittal required.
3.
Contract Float  Days between the Contractors anticipated date for completion
of the Work, or of a specified portion of the Work, if any, and the
corresponding Contract Time.
4.
CPM Schedule  The Progress Schedule based on the Critical Path Method
(CPM) of scheduling. The term Critical Path means any continuous sequence
of Activities in the Progress Schedule controlling, because of their sum
duration, the Early Date of a pertinent, specified Contract Time.
5.
Early/Late Dates  Early/late times of performance, based on CPM
01310 - 1
6.
7.
8.
9.
1.03
calculations, for an Activity in the Progress Schedule. Early Dates will be
based on proceeding with all or part of the Work on the date when the
corresponding Contract Time commences to run. Late Dates will be based on
completing all or part of the Work on the corresponding Contract Time, even
if the Contractor plans early completion.
Milestones  Key, pre-determined points of progress in the completion of a
facility, denoting interim targets in support of the Contract Times. Milestones
may pinpoint targets for key excavation and substructure events, significant
deliveries, critical path transition from superstructure to piping and electrical
roughing and building enclosure. Also, hookup of mechanical and electrical
equipment, availability of power for testing, equipment shakedown, training
of County personnel, start-up, Substantial Completion and other events of
like import.
Official Schedule  The Initial or most recent Revision Submittal accepted by
the County or returned as no resubmittal required and the basis for Payment
Submittals until another Revision Submittal is submitted and accepted. The
accepted Initial Submittal is also the As-Planned Schedule.
Payment Submittal  A monthly Progress Schedule update reflecting progress
and minor adjustments on the Activities, sequencing and restraints for Work
remaining.
Total Float  Days by which an activity may slip from its Early Dates without
necessarily extending a pertinent Contract Time. Total Float at least equals
Contract Float. Total Float may also be calculated and reported in working
Days. When an activity is delayed beyond Early Dates by its Total Float it
becomes a Critical Path activity and if delayed further will impact a Contract
Time.
QUALITY ASSURANCE
A.
The Contractor may self-perform the Work covered by this Section or employ a
Subcontractor, subject to the County's consent. Employment of a scheduling
Subcontractor shall not in any way alter or reduce the Contractor's obligations under
the Contract Documents.
B.
The Contractor will obtain a written interpretation from the County, if the Contractor
believes that the selection of activities, logic ties and/or restraints requires a written
interpretation of the Contract Documents. With each submission, the Contractor will
point out by specific, written notation, any Progress Schedule feature that may reflect
variations from any requirements of the Contract Documents.
C.
It is the Contractor's responsibility to obtain information directly from each
restraints.
D.
Neither Acceptance nor Review of any Progress Schedule will relieve the Contractor
from the obligation to comply with the Contract Times and any sequence of Work
indicated in or required by the Contract Documents and to complete, within the
Contract Times, any Work omitted from that Progress Schedule.
E.
Neither Acceptance nor Review of any Progress Schedule will imply approval of any
01310 - 2
interpretation of or variation from the Contract Documents, unless expressly
approved by the County through a written interpretation or by a separate, written
notation on the returned Progress Schedule Submittal.
1.04
ALLOWANCES – NOT ALLOWED
1.05
MILESTONES AND SCHEDULE RECOVERY
1.06
1.07
A.
The County will select Milestones and Milestone Dates on the basis of the AsPlanned Schedule. As the Official Schedule is revised, Milestone Dates will be
revised accordingly. Milestone Dates will serve as target dates.
B.
Whenever any Activity slips by fourteen (14) or more Days from the Late Date for
an activity in the Official Schedule, Milestone Dates selected by the County, or a
pertinent Contract Time, the Contractor will deliver a Revision Submittal
documenting the Contractor’s schedule recovery plan and/or a properly supported
request for an extension in the Contract Time. The narrative will identify the Delay
and actions taken by the Contractor to recover schedule, whether by adding labor,
Subcontractors or construction equipment, activity re-sequencing, expediting of
submittals and/or deliveries, overtime or shift Work, and so forth. Activity shortening
and overlapping shall be explained as to their basis (and be supported by increases in
resources).
C.
Upon evaluation of that Revision Submittal, if the County determines there is
sufficient cause, the County may withhold liquidated damages or provide a notice of
intent to do so, if schedule is indeed not recovered, and/or may give a notice of
default.
PROGRESS SCHEDULE SOFTWARE
A.
The scheduling software employed by the Contractor to process the Progress
Schedule will be the current version of Primavera P6.0®, or Primavera® Contractor
5.0 CPM scheduling software.
B.
If the Contractor intends to use companion schedule reporting, analysis or graphics
software tools, the Contractor will furnish to the County descriptive materials and
samples describing such software tools.
NON-PERFORMANCE
A.
The County may refuse to recommend all or any part of any payment, if the
Contractor fails, refuses or neglects to provide the required Progress Schedule
information on a timely basis. Partial payments without a properly updated Progress
Schedule shall be returned to the Contractor as non-conforming.
B.
If justified under the circumstances, the County also may prepare alternate Progress
Schedules, as appropriate, and deduct from the Contract Amount all related costs by
Change Order and/or take other action commensurate with the breach.

REPORTS, SCHEDULES AND PLOTS
A.
Schedule Reports will include Activity (ID) code and description, duration, calendar,
Early Dates, Late Dates and Total Float. Separate Schedule Reports will tabulate, for
each Activity, all preceding and succeeding logic types and lead times, whether CPM
Plots displaying logic ties are appended or not.
B.
CPM Schedule Plots will be plotted on a suitable time scale and identify the Contract
Times, Critical Paths, phases and work areas on 24-inch x 36-inch or smaller sheets.
Activities will be shown on the Early Dates with Total Floats noted by Late Date
flags. For Payment and Revision Submittals plot a target comparison based on the
current Official Schedule.
C.
The Activity Value report will tabulate Activity code and description and Activity
Value, percent complete and earned value as calculated by the scheduling software.
Cash flow plots shall be provided showing the monthly and cumulative actual and
planned earned values with curves shown for Early and Late Dates in the schedules.
For Payment and Revision Schedule submittals, the cash flow curves shall also plot
the most current Official Schedule planned earnings curves.
D.
Each submittal shall include listings of all added and deleted activities, logic,
constraints, Activity Value changes and update information vs. the previous Progress
Schedule submittal. This list may be manually prepared or generated by accessory
software that will generate such listings.
NARRATIVE REQUIREMENTS
A.
The Initial Submittal narrative will describe the Contractor’s approach to prosecution
of the Work and the basis for determination of activity durations, sequence and logic,
including the Contractor's management of the site, e.g., lay down, staging, parking,
etc.; Contractor’s phasing of the Work; use of crewing and construction equipment;
identification of non-work County/Professional’s, shifts, weekend Work and
multiple calendars applied to activities and an explanation of the basis for restraint
dates.
B.
Revision and Payment Submittal narratives will explain any changes to the approach
or planning referred to in Paragraph A above on account of any change, delay,
schedule recovery, substitution and/or Contractor-initiated revision occurring since
the previous submittal.
C.
Each narrative will list the Critical Path Activities and compare Early and Late Dates
against Contract Times and Milestone Dates. Narratives shall also recap progress
and Days gained or lost vs. the current Official Schedule, and identify delays, their
extent and causes.
D.
The Initial Submittal narrative will describe all delays occurring since Contract
Award and all pending and anticipated "or equal" and substitution proposals.
Payment and Revision Submittals narratives will describe any new delays and shall
certify that the Contractor has not been delayed, as of the cut off date, by any acts or
omissions of the County, except as otherwise specifically stated.
01310 - 4
1.10
ACTIVITY REQUIREMENTS
A.
Separate activities will identify permits, design when included in the Work,
construction, Submittal preparation and review (and resubmission and re-review),
deliveries (site or storage), testing, start-up, commissioning and Punch List. Separate
Activities will be used for County-furnished equipment, interfaces with other work
and other responsibilities of the County.
B.
Activities will be detailed to the extent required to show the transition of trade Work.
Activities will delineate the progression of the Work through mass excavation,
substructure, superstructure, equipment installation, start of piping and conduit
rough-in, building enclosure, mechanical and electrical equipment hookup phase,
building mechanical, electrical and plumbing (MEP), interior finishes, training of
County personnel, equipment checkout & testing and start-up.
C.
Submittal Activities will segregate long-lead items, any item requiring structural
access and other procurements that, in the Contractor’s judgment, may bear on the
rate of progress. If the Contract Documents require MEP coordination drawings,
separate MEP coordination drawing Activities will be used for each floor. Allow
time for reviews per Section 01300 "Submittals" and the General Conditions, and
revisions and re-submittals. Also include activities for or provide a separate tabular
schedule of submittal dates for all Shop Drawings, product data, and samples
including County furnished products and the dates reviewed submittals will be
required from the County. Indicate decision dates for selection of finishes.
D.
Activities will not combine separate or non-concurrent items of Unit Price or lump
sum Work, Work in separate structures and Work in distinct areas, locations or floors
within an area or structure; or rough-in and finish Work.
E.
Activity durations will equal the work Days required to sufficiently complete the
Work designated by the Activity, (i.e., when finish-to-start successors could start,
even if the Activity is not quite 100% complete). Installation Activities will last from
ten (10) to forty (40) workdays. Submittal review activity durations shall conform to
specified timeframes.
F.
Activities will be assigned consistent descriptions and identification codes. Sort
codes will group Activities by building or structure, floor or area, Change Order and
other meaningful schemes.
G.
Activities will be assigned Activity Values as appropriate and needed to reasonably
allocate the Contract Amount to the time periods that they will be earned and eligible
for payment based on the Progress Schedule and Schedule of Values. Separate pay
activities may be used to simplify cost-loading of the Progress Schedule. When
used, pay activities shall be loaded with the cost of Work that is included, at no cost,
in related (generally, concurrent) CPM activities. Pay activities shall not control the
rate of progress; however, their start and finish dates shall be consistent with those of
their related CPM activities to ensure accurate Early Date and Late Date cash-flow
plots.
01310 - 5
1.11
1.12
FLOAT TOLERANCES AND FLOAT OWNERSHIP
A.
Any Progress Schedule with Early Dates after a Contract Time will yield negative
Total and Contract Floats, whether shown/calculated or not. Any Revision Submittal
with less than negative twenty (20) Days of Float will be returned as "Revise and
Resubmit," unless a time extension is requested or the County assesses liquidated
damages or gives notice of intent to do so, in the event schedule is not recovered.
B.
Float calculated from the definitions given in this Section, supersede any conflicting
Float values in any early completion Progress Schedule.
C.
Neither the County nor the Contractor own the Float time, the Project owns the Float
time. Neither the County nor the Contractor use of positive Total Float will impact a
Contract Completion Date or justify an extension of Contract Time.
SUBMITTALS
A.
Each Progress Schedule Submittal will consist of a narrative, five (5) copies of the
required reports and plots and an optical ROM data disk with the Contractor's
corresponding schedule and schedule layout files in Primavera ".XER" format.
B.
The County will review Progress Schedule Submittals and return a review copy
within 14 Days after receipt and the Contractor shall, if required, resubmit within 7
Days after return of the review copy.
C.
Requirements for the Initial Submittal:
1.
Within twenty (20) Days after receipt of Notice to Proceed and prior to
commencing Work on the Project, prepare and submit to the County the
Initial Submittal of the Progress Schedule for the Work. The Initial Submittal
will show the Work as awarded, without delays, Change Orders or
substitutions.
a.
Activity Values will prorate Schedule of Values costs and/or pay
items through to Activities. Provide a cross-reference listing with two
parts; a part that will list each activity with the respective amounts
allocated from each Schedule of Values and Unit Price Item making
up the total value of each activity and a second part that will list the
Schedule of Values and Unit Price Items with the respective amounts
allocated from each activity that make up the total value of each item.
2.
After the As-Planned Schedule is established, the County will select
Milestones and record the Milestone Early and Late Dates. As the Official
Schedule evolves, Milestone Dates will be revised accordingly.
3.
If the County refuses to endorse the Initial Submittal (or a resubmission) as
"Resubmittal Not Required," the As-Planned Schedule will not be
established. In that event, the Contractor will continue to submit Payment and
Revision Submittals reflecting progress and the Contractor's approach to
remaining Work. The County will rely on the available Payment and
Revision Submittals, subject to whatever adjustments it determines
appropriate.
D.
Requirements for Payment Submittals:
01310 - 6
1.
2.
3.
Payment Submittals with progress up to the closing date and updated Early
Dates and Late Dates for progress and remaining Activities will be due with
each Progress Payment. As-built data will consist of actual dates, percent
complete, earned payment, changes, Delays and other significant events
occurring before the closing date.
Activity percent complete and earned value should indicate a level of
completion that corresponds to the Application for Progress Payment for the
same period. The earned value should be calculated by the scheduling
software as Activity Value times percent complete. Explanation should be
provided whenever the cumulative earned value of activities in a Payment
Submittal is not within 10% of the value of work completed as represented in
the corresponding Application for Progress for Payment.
At the Contractor’s option, a Payment Submittal may overlay minor
adjustments on activities and sequencing for Work remaining. This excludes
Activity re-scoping to reflect Delays, changes, schedule recovery or
substitutions.
E.
Requirements for Revision Submittals:
1.
Revision Submittals will be submitted when necessary because of major
changes or delays affecting activities, sequencing or restraints for Work
remaining and/or to put forth a schedule recovery plan. Revision Submittals
may also be required because of Contractor-initiated re-planning, or when
Contractor plans to perform Work ahead or out-of-sequence that will require
additional testing or inspection personnel, or when requested by the County
when Work is performed out-of-sequence from the current Official Schedule
such that the number of Days gained or lost can not be determined or the
scheduled dates of completion of the Work in a Payment Submittal are not
viewed as reliable.
2.
If requesting a time extension, the Revision Submittal should show the
impact of the delay after incorporating reasonable mitigation to minimize the
impact and illustrate how the number of Days requested time extension was
determined. The delay should be determined as the change in the forecast
Contract Completion Date(s) resulting solely from delays that entitle the
Contractor to a time extension as provided in the General Conditions. Any
and all Contractor slippage and delay occurring prior to and concurrent with
the delay potentially entitling the Contractor to a time extension shall be
incorporated in the Revision and explained such that the concurrent and nonconcurrent periods of delay are indicated. If the Contractor does not follow
the procedures contained in this Section or, if the Contractor's analysis is not
verifiable by an independent, objective evaluation by the County using the
electronic files and data furnished by the Contractor, any such extension in
Contract Time will not be granted.
F.
Retrospective Delay Analysis.
1.
If the County/Professional refuses to endorse any Revision Submittal as
"Resubmittal Not Required," the Contractor and County will use the latest
Official Schedule when evaluating the effect of Delays on Contract Time
and/or Contract Price. The procedure to be used will consist of progressively
updating the latest Official Schedule at key closing dates corresponding to
01310 - 7
2.
starting and finishing dates of the delays and/or dates the delays became
critical or dates the Critical Path may have changed for other reasons. For
each Progress Schedule iteration, slippage between actual Milestone Dates
and Initial Milestone Dates will be correlated to Delays occurring solely in
that iteration.
For each iteration, revisions in Activities, logic ties and restraints affecting
Work after the closing date will be included in that Progress Schedule only if
they meet any of the following conditions. First, they are Progress Schedule
revisions that the County consented to contemporaneously (i.e., before the
closing date) in writing. Second, they reflect comments or objections raised
by or on behalf of the County and that were actually confirmed by the asbuilt progress. Lastly, they represent Contractor’s schedule recovery plans or
other Progress Schedule revisions that were actually confirmed by the asbuilt progress.

SITE INVESTIGATION AND CONTROL
A. Contractor shall verify all dimensions in the field and check field conditions continuously
during construction. Contractor shall be solely responsible for any inaccuracies built into the
Work due to Contractor's failure to comply with this requirement.
B. Contractor shall inspect related and appurtenant Work and report in writing to County any
conditions which will prevent proper completion of the Work. Failure to report any such
conditions shall constitute acceptance of all site conditions, and any required removal, repair,
or replacement caused by unsuitable conditions shall be performed by the Contractor at
Contractor's sole cost and expense.
1.02
INSPECTION OF THE WORK
A. The Work shall be conducted under the general observation of representatives of the County
acting on behalf of the County to ensure strict compliance with the requirements of the
Contract Documents. Such inspection may include mill, plant, shop, or field inspection, as
required. The County shall be permitted access to all parts of the Work, including plants
where materials or equipment are manufactured or fabricated. Inspection by the County are
in addition to the inspections required of Contractor by his QC Representatives.
B. The presence of the County, however, shall not relieve the Contractor of the responsibility

dirt, standing water, staining, chipping or cracking.
F.
All structural and miscellaneous steel and reinforcing steel will be stored off the
ground or otherwise to prevent accumulations of dirt or grease, and in a position to
prevent accumulations of standing water and to minimize rusting. Beams will be
stored with the webs vertical.
G.
Metals will be stored dry, all under cover and vented to prevent build-up of humidity,
all off ground to provide air circulation.
H.
Lumber will be stacked to provide air circulation. Store materials for which a
maximum moisture content is specified in an area where a moisture content can be
maintained.
I.
Gypsum wallboard systems will be stored to protect all metal studs, furring,
insulation boards, batts, accessories and gypsum board to prevent any type of damage
to these materials. Rusted material components, damp or wet insulation or gypsum
boards will not be accepted.
J.
Acoustical materials will be delivered to the job site in unbroken containers labeled
and clearly marked. Materials will not be removed from containers until ready to
install, but will be stored in dry area with cartons neatly stacked. Before installation,
acoustical board will be stored for not less than 24 hours in the Work area at the
same temperature and relative humidity.
K.

E. Asbestos Pipe Handling Best Management Practices
1. Projects will require worker documentation before entering the regulated Work area. A
copy of: their current training certificate (workers and their supervisor); current medical
condition showing the doctor approved their working with asbestos and wearing a
respirator; signed acknowledgment forms; and current record (6-months) of each workers
respirator fit test will be required from all workers.
2. Projects also require air monitoring. OSHA will accept historic data on air monitoring
within 12-months of the Project, provided the data is from a project of like material and
conditions with a crew of the same experience, supervision, and training. Otherwise,
monitoring is required throughout the Project. OSHA requires two (2) types of personnel
air monitoring, full shift and 30-minute excursion level (when highest levels are
anticipated).
3. Some provisions should be made for worker showering or otherwise washing following
work before removing respirators, etc. Even if direct exposure is not anticipated, and at a
minimum, a source of water to rinse the respirators, wash workers faces and hands, and
(in the event of unanticipated direct exposure) some place to shower is required. The
workers will also need a change room and some place to keep their street clothes and
personal possessions.
4. Proposals to remove asbestos pipe sections by cutting must address how the cutting
debris will be captured and kept from becoming airborne. Soil that could be considered
contaminated may also have to be removed.
5. Licensed asbestos abatement Contractors or Subcontractors should have a pollution
endorsement in their liability insurance in case of asbestos fiber release. A contingency
plan, in case the project does not run as smoothly as expected, should be developed and
include emergency phone numbers kept on site during the Project.
6. Daily logs of the asbestos removal work should be kept, and should include sign in
sheets for the workers and whatever air monitoring was done. Accident reports and other
reports or correspondence if something unusual happened should also be included.
7. Waste receipts must be kept through all stages of transport from the site to, and
including, the acceptance at the dumpsite where the material will be abandoned. Amount
of material removed must be equal to the amount of material to be turned into to the
dump.
8. The primary Contractor will give "approval for tear down" at project completion,
indicating that all asbestos removal operations are complete and whether there is a need
for any air monitoring. Air monitoring, if not required by any governing agency or
02080 - 3
OCU Master CIP Technical Specifications
rev: August, 2012
approved permit as discussed previously, may also be required by the County if
documentation to the general public pertaining to contamination is deemed necessary.
This air monitoring is normally done by collecting area samples downwind of the project
at the barrier tape or just inside it. It requires a source of electricity to run the pumps,
which is often provided by a generator.

elevations.
C. Dewatering shall at all times be conducted in such a manner as to preserve the natural
undisturbed bearing capacity of the subgrade soils at proposed bottom of excavation.
D. It is expected that dewatering will be required for pre-drainage of the soils prior to final
excavation for most of the in-ground structures or piping and for maintaining the lowered
groundwater level until construction has been completed so that the structure, pipeline or fill
will not be floated or otherwise damaged.
E. If wellpoints are used, Contractor shall adequately space wellpoints to maintain the
necessary dewatering. Provide suitable filter sand and/or other means to prevent pumping of
fine sands and silts. A continual check shall be maintained by the Contractor to ensure that
the subsurface soil is not being removed by the dewatering operations. Pumping from
wellpoints shall be continuous and standby pumps shall be provided.
F. The Contractor's proposed method of dewatering shall include groundwater observation
wells to determine the water level during construction. Observation wells shall be installed
along pipelines as required to verify depth to water level and at locations approved by the
County.
G. At all times, site grading shall promote drainage. Surface runoff shall be diverted from
excavations. Water entering the excavation from the surface shall be collected in shallow
ditches around the perimeter of the excavation, drained to sumps, and pumped or drained by
gravity to maintain an excavation bottom free from standing water.
H. Flotation shall be prevented by the Contractor by maintaining a positive and continuous
removal of water. The Contractor shall be fully responsible for all damages which may
result from failure to adequately keep excavations dewatered.

02220 - 2
OCU Master CIP Technical Specifications
rev: August, 2012
2. Furnish, put in place, and maintain such sheeting and bracing as may be required to
support the sides of excavations, to prevent any movement which could in any way
diminish the width of the excavation below that necessary for proper construction, to
protect adjacent structures and power poles from undermining, and to protect workers
from hazardous conditions or other damage. Such support shall consist of braced steel
sheet piling, braced wood lagging and soldier beams or other acceptable methods. If the
County is of the opinion that at any point sufficient or proper supports have not been
provided, the County may order additional supports put in at the expense of the
Contractor, and compliance with such order shall not relieve or release the Contractor
from his responsibility for the sufficiency of such supports. Care shall be taken to
prevent voids outside of the sheeting, but if voids are formed, they shall be immediately
filled and compacted. Where soil cannot be properly compacted to fill a void, lean
concrete shall be used as backfill at no additional expense to the County.
3. The Contractor shall construct the sheeting outside the neat lines of the foundation unless
indicated otherwise for the method of operation. Sheeting shall be plumb and securely
braced and tied in position. Sheeting and bracing shall be adequate to withstand all
pressure to which the structure or trench will be subjected. Any movement or bulging
which may occur shall be corrected by the Contractor at their own expense so as to
provide the necessary clearances and dimensions.
4. Where sheeting and bracing is required to support the sides of excavations for structures,
the Contractor shall engage a Professional Geotechnical Engineer, registered in the State
of Florida, to design the sheeting and bracing. The sheeting and bracing installed shall
be in conformity with the design, and the Professional Engineer shall provide
certification of this.
5. The installation of sheeting, particularly by driving or vibrating, may cause distress to
existing structures. The Contractor shall evaluate the potential for such distress and, if
necessary, take all precautions to prevent distress of existing structures because of
sheeting installation.
6. The Contractor shall leave in place to be embedded in the backfill all sheeting and
bracing not shown on the Drawings but which the County may direct him in writing to
leave in place at any time during the progress of the Work for the purpose of preventing
damage to structures, utilities, or property, whether public or private. The County may
direct that timber used for sheeting and bracing be cut off at any specified elevation.
7. All sheeting and bracing not left in place shall be carefully removed in such manner as
not to endanger the construction or other structures, utilities, or property. All voids left
or caused by withdrawal of sheeting shall be immediately refilled with sand by ramming
with tools especially adapted to that purpose, or otherwise as may be directed by the
County.
8. The right of the County to order sheeting and bracing left in place shall not be construed
as creating any obligation on the County’s part to issue such orders, and their failure to
exercise this right shall not relieve the Contractor from liability for damages to persons
or property occurring from or upon the Work occasioned by negligence or otherwise,
growing out of a failure on the part of the Contractor to leave in place sufficient sheeting
and bracing to prevent any caving or moving of the ground.
02220 - 3

9. No wood sheeting is to be withdrawn if driven below mid-diameter of any pipe, and
under no circumstances shall any wood sheeting be cut off at a level lower than 1-foot
above the top of any pipe.
B. Pumping and Drainage:
1. The Contractor shall at all times during construction provide and maintain proper
equipment and facilities to remove all water entering excavations, and shall keep such
excavations dry so as to obtain a satisfactory undisturbed subgrade foundation condition
until the fills, structures, or pipes to be built thereon have been completed to such extent
that they will not be floated or otherwise damaged by allowing the water level to return
to the natural level as stipulated in Section 02140 "Dewatering." The Contractor shall
engage a Professional Geotechnical Engineer registered in the State of Florida to design
the dewatering systems. The Contractor shall submit to the County for a plan for
dewatering systems prior to commencing work. The dewatering system installed shall be
in conformity with the overall construction plan, and the Professional Engineer shall
provide certification of this. The Professional Engineer shall be required to monitor the
performance of the dewatering systems during the progress of the Work and require such
modifications as may be required to assure that the systems are performing satisfactorily.
2. Dewatering shall at all times be conducted in such a manner as to preserve the
undisturbed bearing capacity of the subgrade soils at the proposed bottom of excavation
and to preserve the integrity of adjacent structures. Dewatering by trench pumping will
not be permitted if migration of fine grained natural material from bottom, sidewalls, or
bedding material will occur.
3. Water entering the excavation from surface runoff shall be collected in shallow ditches
around the perimeter of the excavation, drained to sumps, and pumped from the
excavation to maintain a bottom free from standing water.
4. The Contractor shall take all additional precautions to prevent uplift of any structure
during construction.
5. Permission to use any storm sewers or drains for water disposal purposes shall be
obtained from the authority having jurisdiction. Any requirements and costs for such use
shall be the responsibility of the Contractor. However, the Contractor shall not cause
flooding by overloading or blocking up the flow in the drainage facilities, and he shall
leave the facilities unrestricted and as clean as originally found. Any damage to facilities
shall be repaired or restored as directed by the County or the authority having
jurisdiction, at no cost to the County.
6. The Contractor shall prevent flotation by maintaining a positive and continuous
operation of the dewatering system. The Contractor shall be fully responsible and liable
for all damages which may result from failure of this system.
7. Removal of dewatering equipment shall be accomplished after compaction/density
testing has been completed and the system is no longer required. The Contractor shall
remove the material and equipment constituting the system.
8. The Contractor shall take all necessary precautions to preclude the accidental discharge
of fuel, oil, or other contaminates in order to prevent adverse effects on groundwater
quality.

EXCAVATION
A. General: Excavations for roadways, structures, and utilities must be carefully executed in
order to avoid interruption of utility service.
B. Excavating for Roadways/Structures/Utilities:
1. Excavation shall be made to such dimensions as will give suitable room for building the
foundations and the structures, for bracing and supporting, for pumping and draining, and for
all other work required.
a. Excavation for precast or prefabricated structures shall be carried to an elevation 2feet lower than the proposed outside bottom of the structure to provide space for the
select backfill material. Prior to placing the select backfill, the excavation shall be
measured by the County to verify that the excavation has been carried to the proper
depth and is reasonably uniform over the area to be occupied by the structure.
b. Excavation for structures constructed or cast in place in dewatered excavations shall
be carried down to the bottom of the structure where dewatering methods are such
that a dry excavation bottom is exposed and the naturally occurring material at this
elevation leveled and left ready to receive construction. Material disturbed below the
founding elevation in dewatered excavations shall be replaced with Class B concrete.
c. Footings: Cast-in-place concrete footing sides shall be formed immediately after
excavation.
2. Immediately document the location, elevation, size, material type and function of all new
subsurface installations, and utilities encountered during the course of construction.

subsurface obstructions as shown on the Drawings and should anticipate the encounter of
unknown obstructions during the course of the Work.
4. Encounters with subsurface obstructions shall be hand excavated.
5. Excavation and dewatering shall be accomplished by methods that preserve the
undisturbed state of subgrade soils. Subgrade soils which become soft, loose, "quick" or
otherwise unsatisfactory for support of structures as a result of inadequate dewatering or
other construction methods shall be removed and replaced by crushed stone as required
by the County at the Contractor's expense.
6. The bottom of excavations shall be rendered firm and dry before placing any piping or
structure.
7. All pavements shall be cut with saws or approved power tools prior to removal.
8. Excavated material shall be stockpiled in such a manner as to prevent nuisance
conditions. Surface drainage shall not be hindered. Excavated material not suitable for
backfill shall be removed from the site and disposed of by the Contractor.

If more than one pipe is to be installed in a trench, the pipes shall be spaced a
minimum of one foot apart for pipes 4 inches and larger.
M.
If portions of the bottom of trenches consist of material unstable to such a degree
that, in the opinion of the Engineer, it cannot adequately support the pipe or
structure, the bottom shall be over-excavated and stabilized with approved coarse
granular stabilization material. Depth of stabilization shall be as directed by the
Engineer. The initial 10 tons of stabilization shall be incidental to the Contract.
Compensation will be allowed only for such additional quantities as the Engineer
shall direct in writing to be placed.
N.
Do not backfill trenches until tests and inspections have been made.
TRENCH BACKFILLING
A.
Following placement of pipe and inspection of joints, install tamped bedding
material. Place bedding fill materials in layers of 6-inch loose depth.
02320-5
3.06
B.
All bedding and backfill material shall be suitable soils or flowable fill. Backfill
material within 1 foot of pipe and appurtenances shall not contain rock or stone
larger than 2-inch diameter. If a sufficient quantity of suitable material is not
available from the trench or other excavations within the site, provide additional
suitable material or flowable fill.
C.
After completion of bedding and preliminary approval of piping and testing, the pipe
shall be covered to a point one foot above the top of the pipe for the full trench
width, placed in layers of 6-inch loose depth.
D.
Place backfill over pipe. Where trench is within the influence area of roadways,
structures, foundations, or slabs, place backfill in layers of 6-inch loose depth. In all
other areas, place backfill in layers of 8-inch loose depth.
E.
Take necessary precautions not to cause settlement or damage to adjacent slabs,
walls, structures, or foundations. Place backfill and fill materials evenly adjacent to
structures, without wedging against structures or displacement of piping or conduit.
MINOR STRUCTURAL EXCAVATION AND BACKFILLING
A.
Minor structures are defined as manholes, junction boxes, inlets, valve vaults, and
meter vaults. Do not excavate for any structure until that structure is scheduled for
construction. Excavate only to the depth and dimensions necessary for the
construction.
B.
The bottom of all excavations shall be undisturbed earth unless otherwise indicated,
and shall be approved by the Engineer before any subsequent work is started.
C.
Excavations carried below depths indicated on the Drawings without the previous
approval of the Engineer shall be filled with 2500-psi concrete or flowable fill to the
correct level at the expense of the Contractor.
D.
Maintain excavations in good order. If the bearing capacity of the foundation soils is
reduced because the excavation is allowed to remain open prior to commencing
work, the weathered soil shall be removed and replaced with 2500 psi concrete or
flowable fill at the expense of the Contractor.
E.
Do not backfill until new concrete has properly cured, coatings have been approved,
and any required tests have been accepted.
F.
Exercise care during backfilling operations to avoid any puncture, break or other
damage to waterproofing systems, if any. Backfill adjacent to waterproofing shall be
performed in the presence of the Engineer.
G.
Where backfilling is required on both sides of structures, backfill and compact
simultaneously on opposite sides in even layers. Other backfilling sequences shall be
as specifically noted.
02320-6
3.07
3.08
3.09
COMPACTION
A.
Unless otherwise indicated, the type of equipment and number of passes required to
obtain the specified degree of compaction shall be determined at the site, subject to
the approval of the Engineer.
B.
Provide mechanical compaction for cohesive material and vibratory compaction for
granular materials, unless otherwise approved by the Engineer. Vibratory
compaction is not allowed within 100 feet of existing structures. In these areas,
compaction shall be accomplished by static means only. If compaction difficulties
arise, the Engineer shall be consulted to review and possibly modify compaction
procedures.
C.
Noncohesive soils shall be compacted with vibrating roller or equivalent; cohesive
soils shall be compacted with sheeps-foot roller, pneumatic tamping, or approved
equivalent, unless otherwise indicated.
D.
Before compaction, moisten or aerate each layer as necessary to provide optimum
moisture content. Do not place backfill or fill material on surfaces that are muddy,
frozen, or contain frost or ice.
TESTING AND CLEANUP
A.
Provide for testing and cleanup as soon as practicable, so these operations do not lag
far behind pipe installation. Perform preliminary cleanup and grading operations
immediately after backfilling.
B.
All surplus excavated material shall be disposed of by the Contractor.

3.03
3.04
APPLICATION OF STABILIZING MATERIAL
A.
When additive stabilizing materials are required, spread the designated quantity
uniformly over the area to be stabilized.
B.
When materials from an existing base are to be used in the stabilizing at a particular
location, place and spread all of such materials prior to the addition of other
stabilizing additives
C.
Spread commercial stabilizing material by the use of mechanical material spreaders,
except that where use of such equipment is not practicable, use other means of
spreading, but only upon written approval of the proposed alternate method.
MIXING
A.
Perform mixing using rotary tillers or other equipment meeting the approval of the
Engineer. The Contractor may mix the materials in a plant of an approved type
suitable for this work. Thoroughly mix the area to be stabilized throughout the entire
depth and width of the stabilizing limits.
B.
Perform the mixing operations, as specified, (either in place or in a plant) regardless
of whether the existing soil, or any select soils placed within the limits of the
stabilized sections, have the required bearing value without the addition of stabilizing
materials.
MAXIMUM PARTICLE SIZE OF MIXED MATERIALS
At the completion of the mixing, ensure that the gradation of the material within the limits of
the area being stabilized is such that 97% will pass a 3½ inch sieve and that the material
does not have a plasticity index greater than eight or liquid limit greater than 30. Note that
clay balls or lumps of clay size particles (2 microns or less) and therefore cannot be
considered as individual particle sizes. Remove any materials not meeting the plasticity
requirements from the stabilized area. The Contractor may break down or remove from the
stabilized area materials not meeting the gradation requirements.
3.05
COMPACTION
Compact the materials at a moisture content permitting the specified compaction. If the
moisture content of the material is improper for attaining the specified density, either add
water or allow the material to dry until reaching the proper moisture content for the specified
compaction.
3.06

3.07
3.08
CONDITION OF COMPLETED SUBGRADE
A.
After completing the stabilizing and compacting operations, ensure that the subgrade
is firm and substantially unyielding to the extent that it will support construction
equipment and will have the bearing value required by the plans.
B.
Remove all soft and yielding material, and any other portions of the subgrade which
will not compact readily, and replace it with suitable material so that the whole
subgrade is brought to line and grade, with proper allowance for subsequent
compaction.
MAINTENANCE OF COMPLETED SUBGRADE
After completing the subgrade, maintain it free from ruts, depressions, and any damage
resulting from the hauling or handling of materials, equipment, tools, etc. The Contractor is
responsible for maintaining the required density until the subsequent base or pavement is in
place including any repairs, replacement, etc., of curb and gutter, sidewalk, etc., which might
become necessary in order to recompact the subgrade in the event of underwash or other
damage occurring to the previously compacted subgrade. Perform any such recompaction at
no expense to the Owner. Construct and maintain ditches and drains along the completed
subgrade section.
3.09
FIELD QUALITY CONTROL

Submit for approval a design mix for the soil proposed for use in soil-cement
construction prepared by a testing laboratory approved by the Engineer. With the
design mix submittal, include the results of tests run to verify that the soil meets the
requirements, results of tests used to establish the cement content, and a final design
laboratory sample. Submit the design mix to the Engineer for approval a minimum
of 60 calendar days prior to beginning of soil-cement construction for Brush Loss
Design Method or 15 calendar days prior to beginning of soil-cement construction
for Strength Design Method. Express the cement as a percentage of the dry unit
weight of the soil. For mixed-in-place construction, the use a rate of application of
cement based on the maximum density of the soil, determined in accordance with
AASHTO T 99 and rounded up to the nearest pound per cubic yard.
B.
When proportioning the soil-cement mixture in accordance with strength design,
determine the minimum cement content using FM 5-520. Achieve the design
compressive strength specified in seven days. Ensure that the cement content is not
less than 5% by weight, except as noted below.
02717-2
C.
When proportioning the soil-cement mixture in accordance with Brush Loss Design
criteria, determine the minimum cement content in accordance with AASHTO T 135.
Ensure that the cement content is not less than 5% by weight, except as noted below.

D.
When proportioning of soil-cement mixture by the Brush Loss Design Criteria
Method and processing by Central-Plant-Mixing where the requirements noted below
are met, the Engineer will not require strength testing of field specimens. Verify the
properties of the parent material during the processing, on a random frequency, to
ensure that the final mix has not changed from the original design. Provide the
Engineer a printout of each day's production that shows proportioning of the mixture
meets the approved Brush Loss Design, including cement.
E.
Do not apply the minimum 5% cement content specified above if obtaining the soil
material used in producing a soil-cement mixture from a commercial source (not to
exclude recycled materials) where soil properties are consistently uniform, and if
processing the mixture in a central mix plant that automatically weighs components
and automatically records the weight of each component on a printed ticket, tape, or
other digital record.
PART 3 EXECUTION
3.01
GENERAL

condition and that will produce results meeting the requirements for cement application, soil
pulverization, mixing water application, compaction, finishing, and curing, as required
herein. Use compaction equipment that will produce the required density.
3.02
SUBGRADE PREPARATION
A.
Before beginning base construction operations, complete the subgrade. Ensure that
the subgrade is firm enough to support the equipment used in the soil-cement base
operations without appreciable distortion or displacement. Remove any unsuitable
material, and replace it with suitable material.
B.
When constructing the base with central-plant-mixed soil-cement, grade and shape
the subgrade to the lines, grades, and typical cross-section shown in the plans.
Ensure that the subgrade is moist but not ponded at the time of placing the mixed
base course material.
02717-3
3.03
BASE SOIL FOR MIXED-IN-PLACE PROCESSING
Grade and shape the area over which the base is to be constructed to an elevation which will
provide a base in conformance with the grades, lines, thickness, and typical cross-sections
shown on the plans. Remove all roots, sticks, and other deleterious matter during processing.
3.04
3.05
PROCESSING OF SOIL-CEMENT MIXTURE
A.
Mix the soil, cement, and water either by mixed-in-place or central-plant-mix
methods.
B.
Do not allow the percentage of moisture in the soil at the time of cement application
to exceed the quantity that will permit a uniform and intimate mixture of soil and
cement during mixing operations.
C.
During seasons of freezing temperature, do not spread any cement or soil-cement
mixture unless the ambient temperature is at least 40 degrees F in the shade.
D.
At the completion of moist-mixing, pulverize the soil so that 100% passes a 1.5 inch
sieve, 95 to 100% passes the 1 inch sieve and a minimum of 80% passes a No. 4
sieve, exclusive of gravel, shell, or stone.
E.
Complete operations within a period of four hours starting at the time mixing
commences.
MIXED-IN-PLACE METHOD
A.
Where feasible, process the entire width of the base in a single operation. Uniformly
spread the design quantity of cement on the soil at the required rate of application, by
means of an approved method. Replace spread cement that becomes displaced
before starting mixing. Check the uniformity of spread rate by:
1.
2.
Weight of cement spread/square yards covered for a short trial section that is
between 100 and 300 feet in length or
Use of a square yard cloth/box.
B.
After applying the cement, begin mixing within 60 minutes. Initially mix the soil and
cement until the cement has sufficiently blended with the soil to prevent formation of
cement balls when applying additional water; then add water if necessary, and re-mix
the soil-cement mixture. Do not perform windrow mixing.
C.
Process up to the full depth in one course, provided the distribution of cement and
water and the specified density are satisfactory to the Engineer. If not, construct
courses of such thickness to obtain satisfactory results. Make provisions to achieve
adequate bonding between courses.
D.
Immediately after mixing of the soil and cement, add any additional water that is
necessary. If the moisture content exceeds that specified, manipulate the soil-cement
mixture by re-mixing or blading as required to reduce the moisture content to within
02717-4
the specified range. Avoid excessive concentrations of water. Continue mixing
during and after applying water until obtaining a uniform and intimate mixture of
soil, cement, and water.
E.
3.06
3.07
As an alternative to the above described procedure, the use an approved machine that
will blend the cement and the soil and then add and mix-in any additional water that
is necessary.
CENTRAL-PLANT-MIXED METHOD
A.
Mix the soil, cement, and water in a pugmill of either the batch or continuous-flow
type. Equip the plant with feeding and metering devices that will accurately
proportion the soil, cement, and water in the quantities specified. Mix soil and
cement sufficiently to prevent cement balls from forming when adding additional
water. Continue mixing until obtaining a uniform and intimate mixture of soil,
cement, and water.
B.
Haul the mixture to the roadway in trucks equipped with protective covers. Place
the mixture on the moistened subgrade in a uniform layer with suitable equipment.
Do not allow more than 60 minutes to elapse between placing of soil-cement in
adjacent passes of the spreader at any location, except at construction joints. Ensure
that the layer of soil-cement is uniform in thickness and surface contour, and in such
quantity that the completed base will conform to the required grade and crosssection. Do not perform windrow mixing.
CONSTRUCTION JOINTS
Prior to joining any previously constructed section of base, form a vertical construction joint
by cutting back into the completed work to form a true vertical face of acceptable soilcement to the full depth of the base course. Moisten the vertical face, if directed, prior to
placing new material against it.
3.08
SHAPING AND FINISHING
A.
Prior to final compaction, shape the surface of the soil-cement to the required lines,
grades, and cross-section. In all cases where adding soil-cement mixture to any
portion of the surface, lightly scarify the surface with a spring tooth harrow, spike
drag, or other approved device to uniformly loosen the surface prior to adding
material and prior to the initial set of the soil-cement mixture. Compact the resulting
surface to the specified density. Continue rolling until all rutting ceases and until the
base conforms to the density requirements.
B.
Ensure that the surface material is moist but not ponded, and maintained at not less
than 2% below its specified optimum moisture content, during finishing operations.
Perform surface compaction and finishing in such a manner as to produce a smooth
dense surface, free of compaction planes, construction cracks, ridges, and loose
material.
02717-5
C.
3.09
3.10
3.11
If the time limits specified above are exceeded, either remove and replace the base or
leave the base undisturbed for a period of seven days, after which, the Engineer will
examine it to determine its suitability. If found unsuitable, remove and replace the
base at no additional cost to Owner.
COMPACTION
A.
Begin compacting the soil-cement mixture immediately after mixing or placing. Do
not allow more than 30 minutes to elapse between the last pass of moist-mixing or
spreading and the start of compaction of the soil-cement mixture at a particular
location.
B.
Determine the optimum moisture content and the maximum density in the field by
the methods prescribed in AASHTO T 134 on representative samples of the soilcement mixture obtained immediately after the initial mixing. Determine the density
for each day's run or change of material.
C.
Uniformly compact the loose material to meet the density requirements specified
below. During compaction operations, the reshape the material to obtain required
grade and cross-section.
PROTECTION AGAINST DRYING
A.
While finishing and correcting the surface, keep the surface of the base continuously
moist by sprinkling it as necessary until applying the emulsified asphalt curing
material. As soon as practicable, protect the base from drying for seven days by
applying the emulsified asphalt at the rate of 0.20 to 0.25 gallon of the diluted
mixture per square yard. Provide complete coverage without excessive runoff.
While applying the bituminous material, ensure that the soil-cement surface is dense,
free of all loose and extraneous material, and contains sufficient moisture to prevent
excessive penetration of the bituminous materials.
B.
If it is necessary to allow construction equipment or other traffic to use the completed
base before the bituminous material has cured sufficiently to prevent pickup or
displacement, sand the bituminous material, using approximately 10 lbs of clean sand
per square yard. Do not use cover material containing organic acids or other
compounds detrimental to the soil-cement base.
C.
Maintain the curing material during the seven day protection period.
OPENING TO TRAFFIC
Do not allow traffic on the base subsequent to completion of the finishing operations for a
minimum period of 72 hours. As an exception to this requirement, allow equipment
necessary for correction of surface irregularities, application of water, and application of
curing materials on the base, provided that the tire contact pressures of such equipment do
not exceed 45 psi. Under special conditions (i.e. low speed limit, low traffic volume, urban
conditions), the Engineer may waive the 72-hour period.
02717-6
3.12
3.13
3.14
MAINTENANCE
A.
Maintain the base to a true and satisfactory surface until the wearing surface is
constructed. If the Engineer requires any repairing or patching, extend the repair or
patch to the full depth of the base, and make them in a manner that will ensure
restoration of a uniform base course in accordance with the requirements of these
Specifications. Do not repair the base by adding a thin layer of soil-cement or
concrete to the completed work. Make full depth repairs to small or minor areas,
such as at manholes, inlets, or the like, with Class I concrete.
B.
For patching of deficient areas less than 100 square feet and less than 1 inch in depth,
correct the areas using Type S-III Asphalt Concrete. For patching of deficient areas
less than 100 square feet and greater than 1 inch in depth, remove the areas to full
depth, and replace them using Asphalt Base Course Type 3, Type S Asphalt
Concrete, or soil-cement.
DENSITY TESTING REQUIREMENTS
A.
As soon as possible after completing compaction, the perform field density testing to
ensure that the required density is 98% of the maximum density as determined by
methods prescribed in AASHTO T 134.
B.
If an individual test value within a LOT is less than 94% of the maximum density,
determine the extent of this deficiency by performing density tests using a 5 foot grid
pattern until a test value of 95% or greater is located in all directions. Remove the
delineated area of base, and replace it with base meeting all requirements of this
section, at no cost to the Owner.
C.
As an exception to the foregoing, if three or more of the original five individual test
values within a LOT are less than 94% of the maximum density, the Engineer will
reject the entire LOT, and the Contractor shall remove all base within the LOT and
replace it with base meeting all requirements of this Section, at no expense to the
Owner.
SURFACE FINISH ACCEPTANCE REQUIREMENTS
After compacting and finishing, and not later than the beginning of the next calendar day
after constructing of any section of base, measure the surface with a template cut to the
required cross-section and with a 15 foot straightedge laid parallel to the centerline of the
road. Correct all irregularities greater than 1/4 inch to the satisfaction of the Engineer with a
blade adjusted to the lightest cut which will ensure a surface that does not contain
depressions greater than 1/4 inch under the template or the straightedge. The Engineer may
approve other suitable methods for measurement. In the testing of the surface, do not take
the measurements in small holes caused by the blades pulling out individual rocks. Dispose
the material removed.
3.15
THICKNESS ACCEPTANCE REQUIREMENTS
A.
Construction tolerances for thickness are as follows:
02717-7
Central-Plant-Mixed Processing
Mixed-in-Place Processing
3.16
Allowable Deviation From Plan Thickness
-1 inch
+/- 1 inch
B.
When any thickness measurement is outside the construction tolerance, the Engineer
will take additional thickness measurements at 10 foot intervals parallel to the
centerline in each direction from the measurement which is outside the construction
tolerance until a measurement in each direction is within the construction tolerance.
C.
The Engineer will evaluate an area of base found to have a thickness outside the
construction tolerance and, at its discretion will require the Contractor to remove and
replace it with acceptable base of the thickness shown in the plans, at no expense to
the Owner.
STRENGTH TESTING OF FIELD SPECIMENS
A.
Check the adequacy of cement content and uniformity of distribution of cement
within the base by sampling and testing the completed mix.
B.
Take samples at the project site just prior to final compaction and determine a
minimum of two Strength Test Values (STV) each day, with at least one STV per
each 2,500 square yards mixed.
C.
Ensure that each STV is the average strength value of a minimum of three individual
specimens, and for discarding any obvious outliers.
D.
Take representative samples of the mixed soil-cement material for determining an
STV just prior to final compaction, recording the sample location, and ensuring that
the samples are large enough to mold three or more compressive strength test
specimens as prescribed in FM 5-520.
E.
Mold these test specimens at the field moisture content and cast the individual test
specimens as close to identical as possible
F.
Rest the molds, during compaction of strength test specimens, on a 200 pound
concrete block, or the equivalent thereto, that the Contractor provides
G.
Gently extrude these test specimens from the compaction mold, and carefully placing
them in a moist curing environment (not in direct contact with ponded or moving
water) such as a tightly closed container under wet cloth or burlap at locations where
they will not be disturbed.
H.
Continue the initial field cure for at least 24 hours, and if after 24 hours it is
determined that the specimens have not gained sufficient strength to be moved
without probable damage, continue field curing until the Engineer determines that
each specimen can be safely moved without probable damage occurring. When the
Engineer determines that the specimens can be safely moved, transport them to the
laboratory where they will be cured, as described in the design procedure (FM 502717-8
520), to seven days of age. At seven days of age, test the individual specimen for
determination of compressive stress and ensure that the loading procedure and rates
are the same, as described in FM 5-520.
I.
If an STV is less than 60% of the Laboratory Design Strength, remove and replace
the material represented by the STV, at no expense to the Department.
J.
When the LOT average thickness of soil-cement base is deficient by more than 1
inch and the judgment of the Engineer is that the area of such deficiency should not
be removed and replaced, payment for the area retained will be at 50%.
K.
When multiple deficiencies occur, the applicable percent payment schedule will be
applied to the LOT of base that is identified with each deficiency. The penalty for
each deficiency will be applied separately to the unit price.

Use a bituminous mixture composed of a combination of aggregate (coarse, fine or mixtures
thereof), mineral filler, if required, and bituminous material. Ensure that not more than 20%
by weight of the total aggregate used is silica sand or local materials as defined in FDOT
Specification Section 902. Size, grade and combine the several aggregate fractions in such
proportions that the resulting mixture meets the grading and physical properties of the
verified mix design.
PART 3 EXECUTION
3.01
GENERAL
A.
Meet the general construction requirements specified in FDOT Specification Section
330.
B.
Spread the mixture only when the surface upon which it is to be laid has been
previously prepared, is intact, firm, and properly cured, and is dry. Do not spread
mixture that cannot be finished and compacted during daylight hours.
C.
Deliver the asphalt cement to the asphalt plant at a temperature not to exceed 350F
and equip the transport tanks with sampling and temperature sensing devices
02740-4
meeting the requirements of FDOT. Maintain the asphalt cement in storage within a
range of 230 to 350F in advance of mixing operations. Maintain constant heating
within these limits, and do not allow wide fluctuations of temperature during a day's
production.
D.
3.02
3.03
Produce a homogeneous mixture, free from moisture and with no segregated
materials, that meets all specification requirements for the mixture, including
compliance with the Marshall Properties. Also apply these requirements to all mixes
produced by the drum mixer process and all mixes processed through a hot storage
or surge bin, both before and after storage.
PREPARATION OF APPLICATION SURFACES
A.
Prior to the laying of the mixture, clean the surface of the base or pavement to be
covered of all loose and deleterious material by the use of power brooms or blowers,
supplemented by hand brooming where necessary.
B.
Where an asphalt mix is to be placed on an existing pavement or old base which is
irregular, and wherever the plans indicate, bring the existing surface to proper grade
and cross-section by the application of patching or leveling courses.
C.
Where an asphalt mix is to be placed over a newly constructed surface treatment,
sweep and dispose of all loose material from the paving area.
D.
Paint all structures which will be in actual contact with the asphalt mixture, with the
exception of the vertical faces of existing pavements and curbs or curb and gutter,
with a uniform coating of asphalt cement to provide a closely bonded, watertight
joint.
E.
Apply a tack coat, as specified in FDOT Specification Section 300, on existing
pavement structures that are to be overlaid with an asphalt mix and between
successive layers of all asphalt mixes.
PLACING MIXTURE
A.
Lay all asphaltic concrete mixtures, including leveling courses, other than adjacent to
curb and gutter or other true edges, by the stringline method to obtain an accurate,
uniform alignment of the pavement edge.
B.
For each paving machine operated, use a separate crew, each crew operating as a full
unit. The Contractor's Certified Paving Technician in charge of the paving operations
may be responsible for more than one crew but must be physically accessible to the
Engineer at all times when placing mix.
C.
Check the depth of each layer at frequent intervals, and make adjustments when the
thickness exceeds the allowable tolerance. When making an adjustment, allow the
paving machine to travel a minimum distance of 32 feet to stabilize before the second
check is made to determine the effects of the adjustment.
02740-5
3.04
3.05
D.
In limited areas where the use of the spreader is impossible or impracticable, the
Contractor may spread and finish the mixture by hand.
E.
Straightedge and back-patch after obtaining initial compaction and while the material
is still hot.
F.
Upon arrival, dump the mixture in the approved mechanical spreader, and
immediately spread and strike-off the mixture to the full width required, and to such
loose depth for each course that, when the work is completed, the required weight of
mixture per square yard [square meter], or the specified thickness, is secured. Carry
an excess amount of mixture ahead of the screed at all times. Hand rake behind the
machine as required.
G.
Construct each course in layers of the thickness shown on Roadway and Traffic
Design Standards, Index No. 513.
H.
Before starting any rolling, check the surface; correct any irregularities; remove all
drippings, fat sandy accumulations from the screed, and fat spots from any source;
and replace them with satisfactory material. Do not skin patch. When correcting a
depression while the mixture is hot, scarify the surface and add fresh mixture.
APPLICATION OF LEVELING COURSES
A.
Before spreading any leveling course, fill all depressions in the existing surface more
than 1 inch deep by spot patching with leveling course mixture, and then compact
them thoroughly.
B.
Place all courses of leveling by the use of two motor graders, equip one with a
spreader box. Use other types of leveling devices after they have been approved by
the Engineer.
C.
When the total asphalt mix provided for leveling exceeds 50 lb/yd2 [27 kg/m2], place
the mix in two or more layers, with the average spread of any layer not to exceed
50 lb/yd2 [27 kg/m2]. When using Type S-3 Asphaltic Concrete for leveling, do not
allow the average spread of a layer to be less than 50 lb/yd2 [27 kg/m2] or more than
75 lb/yd2 [40 kg/m2]. The quantity of mix for leveling shown in the plans represents
the average for the entire project; however, the Contractor may vary the rate of
application throughout the project as directed by the Engineer. When leveling in
connection with base widening, the Engineer may require placing all the leveling mix
prior to the widening operation.
COMPACTING MIXTURE
A.
The coverage is the number of times the roller passes over a given area of pavement.
Regardless of the rolling procedure used, complete the final rolling before the
surface temperature of the pavement drops below 160F.
B.
Seal Rolling: Provide two coverages with a tandem steel-wheeled roller (either
vibratory or static), weighing 5 to 12 tons, following as close behind the spreader as
02740-6
possible without pick-up, undue displacement, or blistering of the material. Use
vibratory rollers in the static mode for layers of 1 inch or less in thickness.
C.
Intermediate Rolling: Provide five coverages with a self-propelled pneumatic-tired
roller, following as close behind the seal rolling operation as the mix will permit.
D.
Final Rolling: Provide one coverage with a tandum steel-wheeled roller (static mode
only), weighing 5 to 12 tons, after completing the seal rolling and intermediate
rolling, but before the surface pavement temperature drops below 160F.
E.
Operate the self-propelled, pneumatic-tired roller at a speed of 6 to 10 mph. For
each roller, do not exceed an area of coverage of 4,000 yd2/h if rolling Type S
Asphaltic Concrete, do not exceed an area of coverage of 3,000 yd2/h.
F.
Use a sufficient number of self-propelled pneumatic-tired rollers to ensure that the
rolling of the surface for the required number of passes does not delay any other
phase of the laying operation and does not result in excessive cooling of the mixture
before completing the rolling. In the event that the rolling falls behind, discontinue
the laying operation until the rolling operations are sufficiently caught up.
G.
Use hand tamps or other satisfactory means to compact areas which are inaccessible
to a roller, such as areas adjacent to curbs, headers, gutters, manholes, etc.
H.
Use self-propelled pneumatic-tired rollers to roll all patching and leveling courses.
Where placing the initial leveling course over broken concrete pavement, use a
pneumatic-tired roller that weighs at least 15 tons. For Type S-3 Asphaltic Concrete
leveling courses, use a steel-wheeled roller to supplement the traffic rollers. On other
leveling courses, use a steel-wheeled roller to supplement the traffic rollers on all
passes after the first pass.
I.
Do not allow the rollers to deposit gasoline, oil, or grease onto the pavement.
Remove and replace any areas damaged by such deposits as directed by the
Engineer. While rolling is in progress, test the surface continuously, and correct all
discrepancies to comply with the surface requirements. Remove and replace all
drippings, fat or lean areas, and defective construction of any description. Remedy
depressions that develop before completing the rolling by loosening the mixture and
adding new mixture to bring the depressions to a true surface. Should any depression
remain after obtaining the final compaction, remove the full depth of the mixture,
and replace it with sufficient new mixture to form a true and even surface. Correct
all high spots, high joints, and honeycombing as directed by the Engineer. Remove
and replace any mixture remaining unbonded after rolling. Correct all defects prior
to laying the subsequent course.
J.
Use a self-propelled pneumatic-tired roller on the first structural layer placed on a
milled surface. Compact with a minimum of three passes.
02740-7
3.06
3.07
3.08
JOINTS
A.
Place the mixture as continuously as possible. Do not pass the roller over the
unprotected end of the freshly laid mixture except when discontinuing the laying
operation long enough to permit the mixture to become chilled. When thus
interrupting the laying operation, construct a transverse joint by cutting back on the
previous run to expose the full depth of the mat.
B.
For all layers of pavement except the leveling course, place each layer so that
longitudinal construction joints are offset 6 to 12 inches laterally between successive
layers.
C.
When laying fresh mixture against the exposed edges of joints (trimmed or formed
as provided above), place it in close contact with the exposed edge to produce an
even, well-compacted joint after rolling.
SURFACE REQUIREMENTS
A.
Obtain a smooth surface on all pavement courses placed, and then straightedge all
intermediate and final courses with a 15 foot rolling straightedge. Furnish a 15 foot
[4.572 m] manual straightedge, and make it available at the job site at all times
during the paving operation for checking joints and surface irregularities.
B.
Produce a finished surface of uniform texture and compaction with no pulled, torn, or
loosened portions and free of segregation, sand streaks, sand spots, or ripples.
ACCEPTANCE REQUIREMENTS
A.
Upon completion of the final surface or friction course, the Engineer will test the
finished surface with a 15 foot rolling straightedge. Correct all deficiencies in excess
of 3/16 inch.
B.
If correction is made by removing and replacing the pavement, remove the full depth
of the course and extend at least 50 feet on either side of the defective area for the
full width of the paving lane.
C.
If correction is made by overlaying, cover the length of the defective area and taper
uniformly to a featheredge thickness at a minimum distance of 50 feet on either side
of the defective area. Extend the overlay the full width of the roadway. Maintain the
specified cross slope. The Engineer may adjust, as necessary, the mix used for the
overlay for this purpose.
D.
The maximum deficiency from the specified thickness as follows:
1.
2.
E.
For pavement of a specified thickness of 2½ inches or more: ½ inch
For pavement of a specified thickness less than 2 ½ inches: ¼ inch
Where the deficiency in thickness is: (1) in excess of 3/8 inch for pavement of less
than 2½ inches in specified thickness, or (2) in excess of ¾ inch for pavement of
02740-8
specified thickness of 2 ½ inches or more, correct the deficiency either by replacing
the full thickness for a length extending at least 50 feet from each end of the deficient
area.
F.
3.09
For any case of excess deficiency of the pavement, if approved by the Engineer for
each particular location, correct the deficient thickness by adding new surface
material, and compact it to the same density as the adjacent surface. The Engineer
will determine the area to be corrected and the thickness of new material added.
REPAIR AND RESTORATION
Replace pavement or roadway surfaces cut or damaged to equal or better condition than the
original, including stabilization, base course, surface course, curb and gutter, and other
appurtenances.

3.03
INSTALLATION
A. General
1. Alternative methods of liner insertion, pressurization, and processing may be used for
products and processes approved by the County, and when the final liner product meets
the intent of ASTM installation procedures as determined by the County. Installation
shall be in accordance with manufacturer's recommendations, which shall be available
for verification by the inspector. Should there be any difference between the
requirements, the more stringent shall govern. Prior to construction, the Contractor shall
submit to the County such written information which shall include, but not be limited to,
storage and handling of liner before installation, preparing liner for installation, installing
the liner in the sewer pipe, temperature and pressure requirements for inverting and
setting the liner, curing and cool down procedures, end seals and service connections.
The Contractor shall also submit to the County, a description of his methods for avoiding
liner stoppage due to conflict and friction at such locations as the manhole entrance and
the bend into the pipe entrance. The Contractor shall also present plans for dealing with
a liner stopped by snagging within the pipe.
2. Seal the area where the line enters or leaves each manhole. Finish the inside of the
manhole with a quick set cement grout to raise the invert to the grade of the liner pipe.
Also use this grout to dress up around the end of the liner. This space may be sealed
with a mechanical seal, chemical seal, or combination of both. The Contractor shall seal
the liner at all manhole reconnections with an approved product, compatible with the
liner, to completely seal any annular space present.
3. If the pipe liner fails to make a tight seal due to broken or misaligned pipe at the manhole
wall or other reason, the Contractor shall apply a seal at that point.
4. The temperature of water discharged to the sewer system from processing liners shall not
exceed 100°F maximum or the level allowed by State or Local standards. When draining
water, care shall be exercised not to create a vacuum in the line.
5. After the liner has been installed, all active, existing services shall be temporarily
reinstated to 100% of the original opening. This shall be done without excavation in
pavement areas, and in the case of non-man-entry pipes, from the interior of the pipeline
by means of a 360° (degree) television camera and a cutting device that re-establishes the
service connection. When a remote cutting device is used and a cleanout is available,
then a mini-camera down the service may also be used to assist the operator in cutting or
trimming. All coupons shall be recovered at the downstream manhole and removed.
6. The Contractor shall immediately notify the County of any construction delays taking
02771 - 9
OCU Master CIP Technical Specifications
rev: August, 2012
place during the insertion operation. Such delays shall possibly require sampling and
testing by an independent laboratory of portions of the cured liner at the County's
discretion. The cost of such test shall be borne by the Contractor and no extra
compensation will be allowed. Any failure of sample tests or a lack of immediate
notification of delay shall be automatic cause for rejection of that part of the Work at the
County's discretion.
7. The cost for maintaining sanitary sewer service for the property owners during
construction shall be included in the prices bid and no additional compensation will be
allowed. Prior to construction, the Contractor shall submit to the County for review a
complete description of the methods he intends to use to reconnect the existing laterals.
B. Cured-In-Place Liner
1. The Contractor shall designate a location where the reconstruction tube will be vacuum
impregnated prior to installation. The Contractor shall allow the County to inspect the
materials and "wet out" procedure. A catalyst system compatible with the resin and
reconstruction tube shall be used. Sufficient excess resin will be provided to insure
excretion into cracked pipe and or joints of the hot pipe after curing.
2. The wet out reconstruction tube shall be inserted through an existing manhole or other
approved access by means of an inversion process, pulled in place process, or other
approved method, and the application of a hydrostatic head, or equivalent pressure
sufficient to fully extend it to the next designated manhole or termination point. The
reconstruction tube shall be inserted into the vertical inversion standpipe with the
impermeable plastic membrane side out. At the lower end of the inversion standpipe, the
reconstruction tube shall be turned inside out and attached to the standpipe so that a leak
proof seal is created. The inversion head will be adjusted to be of sufficient height to
cause the impregnated tube to invert from manhole to manhole and hold the tube tight to
the pipe wall, produce dimples at side connections and flared ends at the manholes. The
use of a lubricant is recommended. Care shall be taken during the elevated curing
temperature so as not to overstress the felt fiber.
3. After inversion is completed the Contractor shall supply suitable heat source and
recirculation equipment. The equipment shall be capable of delivering the heat source
throughout the section uniformly to raise the temperature above the temperature required
to affect a cure of the resin. This temperature shall be determined by the resin/catalyst
system employed. The system, together with the manufacturer's approval, shall be
submitted to the County for review prior to lining operations. Temperatures shall be
monitored and recorded throughout the installation process to ensure that each phase of
the process is achieved at the manufacturer's recommended temperature levels. Copies
of these records shall be given to the County at the completion of each installation.
4. The heat source shall be fitted with suitable monitors to gauge the temperature of the
incoming and outgoing heat source. Another such gauge shall be placed between the
impregnated reconstruction tube and the pipe invert at the remote manhole to determine
the temperatures during cure. The resin manufacturer shall recommend temperature in
the line during the cure period.
5. Initial cure shall be deemed to be completed when inspection of the exposed portions of
cured pipe appear to be hard and sound and the remote temperature sensor indicates that
the temperature is of a magnitude to realize an exotherm. The cure period shall be of a
duration recommended by the resin manufacturer, as modified for the cured-in-place
inversion process, during which time the recirculation of the heat source and cycling of
02771 - 10
OCU Master CIP Technical Specifications
rev: August, 2012
the heat exchanger to maintain the temperature continues. Contractor shall retain a resinimpregnated sample (wick) to provide verification of the curing process taking place in
the host pipe.
6. The Contractor shall cool the hardened pipe to a temperature below 100°F before
relieving the static head in the inversion standpipe. Cool-down may be accomplished by
the introduction of cool water into the inversion standpipe to replace water being drained
and disposed per the approved pre-treatment plan. Care shall be taken in the release of
the static head so that a vacuum will not be developed that could damage the newly
installed pipe.
C. Service Lateral Renewal
1. The exact location and number of service connections or side sewers shall be verified
during the initial television inspection. It shall be the Contractor's responsibility to
accurately field locate all existing service connections or side sewers and establish means
for access for flow control. The Contractor shall reconnect all service connections or
side sewers to the liner pipe as indicated in accordance with the Contract Documents.
2. The Contractor shall be responsible for restoring/correcting, without any delay, all
missed or faulty reconnections, as well as any damage caused to property owners for not
reconnecting the services soon enough or for not giving notice to the property owners.
3. Any lateral not initially reinstated by the Contractor that proves to be active shall be
reinstated by the Contractor at no additional cost to the County and the Contractor shall
be responsible for any resulting property damage of floods.
4. All existing service connections shall be reconnected by a remote controlled cutting
device directed internally by a television camera or by internal manual cutting. Cuts
shall be made by experienced operators so that no blind attempts or holes are made in the
liner pipe. Locations shall be verified carefully to match earlier tapes for accurate lateral
location, especially where dimples are not well defined. The County reserves the right to
require service connection by excavation at the Contractor's expense at any location if
the quality or workmanship of the cut is not satisfactory.

PART 3 - EXECUTION
3.01
REHABILITATION OF MANHOLE STRUCTURE
A. General Procedures
1. Safety: The Contractor shall perform all work in strict accordance with all applicable
OSHA, state, local, and manufacturer’s safety standards. Each method of manhole
rehabilitation in this Section requires some degree of manhole entry by workers.
Particular attention is drawn to those safety requirements regarding confined space entry
and respiratory protection from airborne particulate materials during cleaning, product
mixing, and application.
2. Cleaning: All concrete and masonry surfaces to be rehabilitated shall be clean. All grease,
oil, laitance, coatings, loose bricks, mortar, unsound brick or concrete, and other foreign
materials shall be completely removed. Water blasting utilizing a 210°F steam unit and
proper nozzles shall be the primary method of cleaning; however, other methods such as
wet or dry sandblasting, acid wash, concrete cleaners, degreasers, or mechanical means
may be required to properly clean the surface. All surfaces on which these methods are
used shall be thoroughly rinsed, scrubbed, and neutralized to remove cleaning agents and
their reactant products. Debris resulting from cleaning shall be removed from the manhole
and not discharged downstream.
3. Stopping Infiltration: After surface preparation and prior to the application of mortars
and coatings, infiltration shall be stopped either by plugging with a waterstop compound
or chemical grout sealing.
4. Patching: All large holes or voids around joints, or pipes and all spalled areas and all
holes caused by missing or cracked brick shall be patched. All missing mortar shall be
repointed using a non-shrink patching mortar. All cracked or disintegrated material shall
be removed from the area to be patched or repointed, exposing a sound sub base. All
cracks not subject to movement and greater than 1/16-inch in width shall be routed out to
a minimum width and depth of 1/2-inch and patched with non-shrink patching mortar.
5. Flow Control: The Contractor shall be responsible for plugging or diverting the flow of
sewage as needed for repair and lining of manhole inverts and benches.
6. Remove all loose grout and rubble from existing channel. Rebuild channel if required by
reshaping and repairing slope of shelves or benches. Work shall include aligning inflow
and outflow ports in such a manner as to prevent the deposition of solids at the transition
point. All inverts shall follow the grades of the pipe entering the manhole. Changes in
direction of the sewer and entering branch or branches shall have a true curve with the
02775 - 4
OCU Master CIP Technical Specifications
rev: August, 2012
largest possible radius and shall be shaped to allow easy entrance of maintenance
equipment including buckets or T.V. camera.
7. Each lining system shall be installed in accordance with the manufacturer’s
recommendation to withstand groundwater pressures. For manholes greater than 12-feet
in depth, the lining shall withstand the pressures associated with a groundwater depth
equal to the manhole depth. Linings for all other manholes shall withstand the pressures
associated with groundwater depth of 12-feet. Measure groundwater depth from
manhole bench to top of ground surface.
8. Application of products shall be by factory certified applicators.
3.02
SPRAY APPLIED LIGHT-WEIGHT STRUCTURAL REINFORCED CEMENT
A. The surface prior to spraying shall be damp without noticeable free water droplets or running
water. Materials shall be spray-applied to a minimum uniform thickness to insure that all
cracks, crevices, and voids are filled and a somewhat smooth surface remains after light
troweling. The light troweling is performed to compact the material into voids and to set the
bond.
B. The first application shall have begun to take an initial set (disappearance of surface sheen,
which could be 15-minutes to 1-hour depending upon ambient conditions) before the second
application to assure a minimum total finished thickness of 1/2-inch. The final finished
thickness may need to be greater than 1/2-inch as recommended by the manufacturer to
withstand groundwater pressures. A depth gauge shall be used during application, at various
locations, to verify the required thickness. The surface then shall be trowelled to smooth
finish with care taken not to over trowel so as to bring additional water to the surface and
weaken it. Manufacturer’s recommendations shall be followed whenever more than 24hours have elapsed between applications.
C. The bench covers used to catch debris shall be removed and the bench and invert sprayed
such that a gradual slope is produced from the walls to the invert with the thickness at the
edge of the invert being no less than 1/2-inch. The wall-bench intersection shall be rounded
to a uniform radius the full circumference of the intersection.
D. No application shall be made to frozen surfaces or if freezing is expected to occur within the
manhole for 24-hours after application. If ambient temperatures are in excess of 95°F,
precautions shall be taken to keep the mix temperature at time of application below 90°F,
using ice if necessary.
E. The final application shall have a minimum of 4-hours cure time before being subjected to
active flow.
3.03
CENTRIFUGALLY CAST STRUCTURAL REINFORCED CEMENT
A. Application procedures shall conform to the recommendations of the manufacturer.
B. The rotating casting applicator shall be positioned to evenly apply the material and be
withdrawn at a rate to assure a final minimum thickness of 1-inch. The final finished
thickness may need to be greater than 1-inch as recommended by the manufacturer to
02775 - 5
OCU Master CIP Technical Specifications
rev: August, 2012
withstand groundwater pressures. A depth gauge shall be used during application, at various
locations to verify the required thickness.
C. The bench covers used to catch debris shall be removed and the bench and invert sprayed or
hand applied so that a gradual slope is produced from the walls to the invert with the
thickness at the edge of the invert being no less than 1/2-inch. The wall-bench intersection
shall be rounded to a uniform radius the full circumference of the intersection.
D. No application shall be made to frozen surfaces or if freezing is expected to occur within the
manhole for 24-hours after application. If ambient temperatures are in excess of 95°F,
precautions shall be taken to keep the mix temperature at time of application below 90°F.
E. The final application shall have a minimum of 1-hour cure time as recommended by the
manufacturer before being subjected to active flow.
3.04
SPRAYED APPLIED EPOXY RESIN SYSTEM
A. Application procedures shall conform to the recommendations of the manufacturer.
B. The epoxy resin shall be sprayed onto the surfaces of the manhole walls, benches, and
inverts to produce a smooth coating and yield the required structural integrity and corrosion
resistance. A depth gauge shall be used during application at various locations to verify the
required thickness.
C. The epoxy resin shall be applied to a minimum thickness of 0.125-inches (125-mils) at the
top of the manhole and gradually thickened in accordance with manufacturer’s
recommendations to withstand groundwater pressures. The application shall have a
minimum cure time as recommended by the manufacturer before being subjected to active
flow.
C. The sloped surface of the manhole bench shall be made non-skid by broadcasting aluminum
oxide or sand into the surface prior to gelatin/set.
3.05
MULTI-COMPONENT LINER SYSTEM
A. Application procedures shall conform to the recommendations of the manufacturer.
B. The liner system shall be sprayed onto the surfaces of the manhole walls, benches, and
inverts to produce a smooth surface. The spray equipment shall be specifically designed to
accurately ratio and apply the liner system.
C. Final installation shall be a minimum of 500-mils.
D. The application shall have a minimum cure time as recommended by the manufacturer
before being subjected to active flow.

PUMPS
A.
The pumps shall be totally submersible non-clog centrifugal pumps with submersible
closed coupled motors designed to pump sewage, capable of passing a minimum 3inch solid. The design shall be such that the pumping units shall be automatically
connected to the discharge piping when lowered into place on the discharge
connection. The pumps shall be easily removable for inspection or service, requiring
no bolts, nuts or other fastenings to be removed for this purpose, and no need for
personnel to enter the pump wet well.
B.
The pump shaft shall be of Series 300 or 400 stainless steel or carbon steel. If a
carbon steel shaft is provided, the pump manufacturer shall demonstrate that any part
of the shaft which will normally come in contact with the wastewater has proven to
be corrosion resistant in this application. The shaft and bearings shall be adequately
designed to meet the maximum torque required for any start-up or operating
condition and to minimize vibration and shaft deflection. As a minimum, the pump
shaft shall rotate on two (2) permanently lubricated bearings. The upper bearing
shall be a single-row ball bearing. The lower bearing shall be a two-row angular
contact ball bearing to minimize vibration and provide maximum bearing life.
C.
Only standard non-trimmed impellers shall be acceptable. Impellers can be of the
closed or open type. The closed type can be single or double vaned. The open type
shall be single vane with a self-cleaning, adjustable cast iron wear plate. All
impellers shall be non-clogged and dynamically balanced. The impeller shall be
constructed of gray cast iron, ASTM A-48, Class 30. The design shall permit low
liquid velocities and gradual acceleration and change of flow direction of the pumped
media. The impeller/casing design shall result in a passage free of surfaces to which
solid or fibrous materials can adhere. The overall pump design shall combine high
efficiency, low required NPSH, large sphere passage and the ability to handle high
solids concentrations efficiently. All other parts shall be of close grain gray iron
construction. The impeller shall be of a centrifugal non-clog type, capable of passing
solids and fibrous material.
D.
Each pump shall be provided with a tandem double mechanical seal running in an oil
reservoir, composed of two separate lapped face seals, each consisting of one
stationary and one rotating tungsten-carbide ring with each pair held in contact by a
separate spring. Lapped seal faces must be hydrodynamically lubricated at a
constant rate. The lower seal unit, between the pump and oil chamber, shall contain
one stationary and one positively driven rotating tungsten-carbide ring.
Silicon-carbide may be used in place of tungsten-carbide for the lower seal. The
upper seal unit, between the oil pump and motor housing, shall contain one stationary
tungsten-carbide ring and one positively driven rotating carbon ring. The
compression spring shall be protected against exposure to the pumped liquid. The
pumped liquid shall be sealed from the oil reservoir by one face seal and the oil
11310-5
reservoir from the motor chamber by the other. The seals shall require neither
maintenance nor adjustment, and shall be easily replaced. Conventional double
mechanical seals with a single spring between the rotating faces, requiring constant
differential pressure to effect sealing and subject to opening and penetration by
pumping forces shall not be considered equal to tandem seals specified and required.
E.
Each pump shall be provided with a replaceable pump wear ring system to provide
efficient sealing between the volute and impeller and allow for replacement to
maintain pump efficiency. As a minimum, one stationary wear ring provided in the
pump volute or one rotating wear ring provided on the pump impeller shall be
required. A two-part wear ring system is also acceptable.
F.
A sliding guide bracket shall be an integral part of the pumping unit. The pump
casing shall have a machined connection flange to connect with the cast iron
discharge connection, which shall be bolted to the floor of the wet-well with stainless
steel anchor bolts and so designed as to receive the pump connection without the
need of any bolts or nuts. Sealing of the pumping units to the discharge connection
shall be accomplished by a simple linear downward motion of the pump with the
entire weight of the pumping unit guided by two (2) type 316 stainless steel guides.
