DIVISION 100 - GENERAL PROVISIONS
SECTION 101 - GENERAL INFORMATION
101.01 General.
THE FOLLOWING IS ADDED:
Pursuant to NJSA 27:1B-21.6, the Commissioner intends to enter into a multi-year contract for the
advancement of the Project. Although the multi-year contract will pledge funds anticipated to be appropriated for
the Project by the Legislature, payment of the moneys pledged is subject to the availability of funds in the fiscal
year (FY) in which the funds are to be appropriated. Only amounts appropriated by law may be expended.
The Commissioner intends to proceed expeditiously with the Project. However, there is no assurance that the
Annual Appropriations Act will contain an appropriation or that the Federal Government will approve or provide
federal funding for the Project. The Legislature has no legal obligation to make such an appropriation. Failure by
the Legislature to appropriate funds or failure by the Federal Government to approve or provide federal funding
sufficient to advance the Project will not constitute a default under, or breach of, any contract entered into by the
State for the construction of the Project. However, if the State terminates the Contract or suspends work under the
Contract because the Legislature has failed to appropriate or the Federal Government has failed to provide or
approve sufficient funding to advance the Project, the parties to the Contract will retain their rights pursuant to the
suspension of work and termination of Contract Provisions of the Project specifications; except as indicated below.
The Contractor shall not expend or cause to be expended any sum in excess of the amount allocated in the
current fiscal year's Capital Program (as specified below). The Department will notify the Contractor when each
level of additional funding has been appropriated by the Legislature or approved or provided by the Federal
Government. Any expenditure by the contractor which exceeds the amount actually appropriated or exceeds the
amount of approved federal funding is at the Contractor's risk and the Contractor waives any right to recover any
sum in excess of that appropriated amount or the amount approved or provided by the Federal Government even if
the State terminates or suspends work under the Contract because the Legislature has failed to appropriate or the
Federal Government has not provided or approved sufficient funds to advance the Project.
The approved 2006 Capital Program has an item with $ 0.75 million for the construction of the Project.
It is anticipated that 0.5 million dollars in additional funds will be provided during State FY 2007.
It should be noted that the Federal FY begins October 1 of the previous calendar year and that the State FY
begins July 1 of the previous calendar each year.
It should be noted that the State FY begins July 1 of the previous calendar year.

108.11 Extensions and Reductions of Contract Time.
THIS SUBSECTION IS CHANGED TO:
A.
Basis for Extension. Where appropriate under the provisions of this Subsection, extensions or
reductions to the Contract Time may be provided by Construction Order, however, such extensions or
reductions will be allowed only to the extent that the increase or decrease in the Work or delays of the
types indicated below affects current controlling operations and the overall Completion. Increases or
decreases in Work or such delays, which do not affect the overall Completion, are not to be the basis for
reduction or extension of Contract Time. Extensions of Contract Time will not be granted under this
Subsection where it is determined that the Contractor could have avoided the circumstances which
caused the request for extension.
If the Contractor is delayed in completion of the Work by reason of changes made under Subsection
104.02, or by failure of the Department to acquire right-of-way, or by any act of other contractors
consistent with Subsection 105.10, or due to the discovery of archeological finds consistent with
Subsection 108.13, or the discovery of hazardous substances, or by any act of the Engineer or of the
Department not contemplated by the Contract, an extension of Contract Time commensurate with the
delay in overall completion of the Contract thus caused will be granted, and the Contractor is relieved
from any claim for liquidated damages or engineering and inspection charges.
Additionally, the Contractor may be granted an extension of Contract Time and not be assessed
liquidated damages or the costs of engineering and inspection for any portion of the delay in overall
completion of the Work beyond the time provided in Subsection 108.10 caused by the following reasons:
1. acts of civil or military authorities, war, or riot;
2. fire;
3. floods, tidal waves, earthquakes, cyclones, tornadoes, hurricanes, or other cataclysmic natural
phenomenon (except on working day contracts);
4. extreme weather conditions (see Item 1 of the fourth paragraph) (except on working day contracts);
5. epidemics or quarantine restrictions;
6. strikes or labor disputes beyond the control of the Contractor which prevent work on the
construction operations which are critical to the completion of the Project;
7. shortages of materials (see Item 2 of the fourth paragraph) or freight embargoes;
8. acts of the State in its sovereign capacity;
9. failure of the Engineer to furnish interpretations of the Contract Documents (see Item 3 of the fourth
paragraph).
B.
Criteria for Evaluation. Extension of Contract Time for the reasons set forth in this Subsection will not
be granted unless the Contractor has notified the Engineer in writing of the causes of delay within 15
State Business Days from the beginning of any such delay on forms provided by the Department. The
Engineer will evaluate the facts and the extent of the delay, and the Engineer's findings will be final and
conclusive and will be based on the following:
1. Extensions of Contract Time for extreme weather conditions will be granted in accordance with the
following:

Extensions of Contract Time for extreme weather conditions will be granted in accordance
with the following for the months of December through March inclusive:
It is anticipated that the average number of total Working Days during this four month winter
period is for road work (Exclusive of temperature sensitive work, for example but not limited to,
paving operations, earthwork, aggregates, curb and sidewalk, etc.) and for bridge work (Exclusive
of temperature sensitive work, for example but not limited to, concrete decks, parapets, bridge
repairs, bridge painting, etc.)
In using the above, the Engineer will:
a. Consider days for which an extension is granted under the above category "floods, tidal
waves, earthquakes, cyclones, tornadoes, hurricanes, or other cataclysmic natural
phenomenon" as days on which the Contractor's work is limited as the result of these
extreme weather conditions;
b. Consider days for which an extension is granted under the above categories for causes
other than "floods, tidal waves, earthquakes, cyclones, tornadoes, hurricanes, or other
cataclysmic natural phenomenon" as days on which the Contractor worked and was
unaffected by extreme weather conditions; and
c. Make the above calculation based on the full number of days in the calendar month as
being days on which the Contractor could have worked without regard to Saturdays,
Sundays, and holidays.
d. Extension of time for extreme weather conditions will only be granted when the Critical
Path of the Progress Schedule is affected and documented by the contractor in
accordance with Subsection108.04. No extension of time will be granted unless the
Contractor submits daily documentation of such extreme weather.
2.
Extensions of Contract Time will not be granted for a delay caused by a shortage of materials unless
the Contractor furnishes:
a. Documentary proof that it has diligently made every effort to obtain such materials from
all known sources within reasonable distance from the Work, and
13
b.
3.
4.
Further proof in the form of a progress schedule, as required in Subsection 108.04,
showing that the inability to obtain such materials when originally planned, did, in fact,
delayed the date of Completion which could not be compensated for by revising the
sequence of the Contractor's operations. The term "shortage of materials" applies only to
raw and fabricated materials, articles, parts, or equipments which are standard items and
do not apply to materials, parts, articles, or equipment which are processed, made,
constructed, fabricated, or manufactured to meet the specific requirements of the
Contract. Only the physical shortage of materials and not the cost of materials will be
considered.
Extensions of Contract Time will not be granted for failure of the Engineer to furnish interpretations
of the Contract Documents until 20 State Business Days after receipt of such demand in writing as
required by Subsections 105.01 and 105.07, and not then unless such request for an interpretation of
the Contract Documents is reasonable and made in good faith, and the failure to respond was
unwarranted.
It is understood and agreed that the Contractor has considered in its bid all of the permanent and
temporary utility facilities in their present or relocated positions as may be shown on Plans, as
described in Specifications and as revealed by its site investigation; is aware that utility company
service demands, adverse field conditions and emergencies may affect the owner's ability to comply
with the proposed schedules for utility work; and is cognizant of the limited ability of the State to
control the actions of the utility companies, including the actions of railroads, and has made
allowances in its bid. Extensions of Contract Time will be granted for extreme weather and exigent
circumstances only, as specifically set forth above and which are outside the control of the
respective utility company(ies) or the Contractor as determined by the Engineer utilizing the
Extreme Weather provisions specified in 1. above. Extension of time for utility work will only be
granted when the Critical Path of the Progress Schedule is affected and documented by the
Contractor in accordance with Subsection108.04.
Except where specifically provided in the Contract Documents, the Contractor shall not make any
claim for damages or additional compensation for any delay in or hindrance to the performance of the
Contract occasioned by any act or omission to act by the State or any of its representatives, or for any of
the reasons enumerated in this Subsection and agrees that any such claim shall be fully compensated for
by an extension of Contract Time to complete performance of the Work.
Extensions of Contract Time will not be granted due to delays caused by, or in any way related to,
the financial condition of the Contractor, subcontractors, sub-subcontractors, material, men, fabricators,
or suppliers. The Contractor and its surety assume full responsibility for ensuring that the financial
condition of any of the above does not delay completion of the Contract.
If, as a result of modifications made under Subsection 104.02, 104.05, 104.06, or 108.09, the Work
required is reduced or altered so that the time required for Completion is reduced, the Engineer may
reduce the Contract Time provided under Subsection 108.10. The Engineer will evaluate the facts and
the extent of the reduction. The Engineer's findings thereon will be final and conclusive.
It is the intention of the above provisions that the Contractor or surety is not relieved of liability for
liquidated damages or engineering and inspection charges for any period of delay in Completion in
excess of that expressly provided for in this Subsection.
108.19 Lane Occupancy Charges.
THE FOLLOWING IS ADDED:
The rate or rates to be applied in the calculation of a Lane Occupancy Charge shall be in accordance with
the following:

SENSOR INSTALLATION
1. Weigh-in-Motion (WIM) System.
Each lane of the WIM site shall be constructed in a loop - axle sensor – loop – axle sensor – loop (L-P-LPL) configuration. Three (3) inductive loops and two (2) weight sensors shall be installed in each lane of traffic in
accordance with the plan. Lengths of weight sensors will not exceed the width of the lanes and shall be ordered
with
enough lead-in cable to be connected to the system electronics inside the cabinet without splices.
When directed, loops shall be installed after milling of the roadway surface. The inductive
loop detector shall be installed prior to installation of the top layer of the surface course and the axle sensor shall be
installed in the top layer of the surface course. The loop edges are to be established using two survey stakes each
for
the leading and trailing edge of each loop. After the overlay, the location of each loop edge is to be re-established
to
facilitate the marking and cutting of the slot for the axle sensor. Accurate measurement of spacing between loops
and sensors are to be maintained so that the system can be properly calibrated. Loop leads are to remain
undisturbed
by any facet of axle sensor installation.
Installation of WIM Axle Sensor will include wet cutting the WIM Axle Sensor slot;
cutting the lead-in cable slot (min. of 2in. deep & 1/8in. wider than the conduit); cleaning the slot by wire brushing
and power washing with fresh water; drying the slot; testing, installing the WIM Axle sensor and WIM Axle sensor
lead-in cable, installing thin wall tubing to the lead in cable (minimum 3/8” ID, flexible PVC or polyethylene
tubing)
from the end of the sensor to the nearest junction box, installing the WIM Axle Sensor encapsulation and lead-in
cable loop sealant; grinding top of the encapsulation material flushed with the road; pulling the lead-in cable
through
the conduit to the cabinet and terminating to the to the WIM computer system with BNC connector.
The Temperature Sensor is usually installed in the shoulder closest to the Control Cabinet. Installation of
the Temperature Sensor will include wet cutting the Temperature Sensor Probe slot, cutting the lead-in cable slot,
cleaning the slot by wire brushing and power washing with fresh water; drying the slot, installing the Sensor
encapsulation and lead-in cable loop sealant, pulling the lead-in cable through the conduit to the cabinet and
terminating to the WIM computer system. Each WIM computer system will have a separate Temperature Sensor.
Piezoelectric Sensor Installation procedure using Roadtrax BL sensors Class 1 by Measurement Specialties
Inc.
1.
Layout and mark the location of the loops and sensor on the road. The sensor should be exactly
perpendicular to the flow of traffic. Shorter sensors (6 feet length) are positioned to one side in a wheel
path, NOT in the center of the lane; longer sensors are typically centered in the lane.
2.
Cut a slot for the sensor ¾” wide and 1” deep. The slot should be 8” longer than the sensor. Wet cut the
slot with ¾” wide diamond blade blades be ganged together to get a single ¾” wide cut. Cut the lead in
21
cable slot, minimum of 2” deep and 1/8” wider than the tubing or flexible conduit. Use high pressure
water and compressed air to clean all foreign matters out of the slot and 6” on all sides of the slot. Dry
the slot and place a strip of duct tape along the pavement 1/8” gap between the edge of the slot and the
tape on both sides for the full length of the slot. No epoxy mixing or placement will begin until the
Engineer has approved all surface cleaning operation.
3.
Check to see that the sensor is straight and flat with no twist or curls. Use an LCR Meter, measure the
capacitance, resistance and dissipation factor of the sensor. Record all results. All capacitance reading
should be within 20% of the reading on the data sheet provided with each sensor. Clean the length of the
brass element of the sensor with steel wool/emery pad.
4.
Place the installation brackets on the sensor every 6” (+/-1”). Make sure all the brackets are facing the
same direction.
5.
Slightly bend down the end of the sensor at 30 deg. angle. Slightly bend down the sensor at the lead
attachment at 15 deg. angle. Then bend it back level, forming a lazy Z. Position the sensor in the slot
starting at the end setting the clips into the slot. The top of the sensor should be exactly 3/8” below the
road surface and the top of the brackets are 1/8” below the surface of the road. The sensor should be the
same depth along the entire length and should not cross any expansion joint or crack in the pavement.
6.
Premix the resin for about 2 minutes or until smooth. Make sure the resin is homogeneous prior to
adding in the hardener. Start pouring a small bead of the resin in the direction of lead cable attachment,
going back to the end pouring another pass and continuing the process until the slot is filled completely.
Lightly trowel the resin smooth and carefully ensuring that it is not over worked. As soon as the resin
starts to cure, remove the tape.
7.
Allow the resin to fully cure and grind off any excess materials flush with the road using an angle
grinder or belt sander. Do not over grind.
8.
Complete the installation by filling the lead in cable slot with loop sealant materials. A thin walled
plastic tubing (minimum 3/8” ID flexible PVC or polyethylene) will contain the lead-in cable. In the
unlikely event that the sensor needs to be replaced, the lead in cable can then be pulled through the
tubing.
9.
Using an LCR meter, perform the final tests on the sensor, including capacitance, resistance and
dissipation factor. Record all results. All capacitance reading should be within 20% of the reading on
the data sheet provided with each sensor.
10. When the cable is routed all the way into the cabinet, cut the cables to the final length. Again, check
capacitance, resistance and dissipation factor. Record all results. The resistance and dissipation factor
should be the same, within 20% of the reading on the data sheet provided with each sensor; the
capacitance will go down at a rate of 2.7 nF/100’ of cable cut off.
11. When the lane is opened to traffic, perform a functional test on the sensor using an oscilloscope. Record
and print curve results.
Vibracoax Class 1 Piezoelectric Sensor:
1.
Layout and mark the location of the loops and sensor on the road. The sensor should be exactly
perpendicular to the flow of traffic. Shorter sensors (6 feet length) are positioned to one side; longer
sensors are typically centered in the lane.
2.
Wet cut the slot into the roadway using a 3/16 inch saw blade set to a depth of 1½ inch. Chip out
material from between the two saw cuts to form the slot where the piezoelectric sensor will go. Cut the
lead in cable slot, minimum of 2” deep and 1/8” wider than the tubing or flexible conduit. Use wire
brush, high pressure water and compressed air to clean all foreign matters out of the slot and 6” on all
sides of the slot. Dry the slot and place a strip of duct tape along the pavement 1/4” gap between the
22
edge of the slot and the tape on both sides for the full length of the slot. No epoxy mixing or placement
will begin until the Engineer has approved all surface cleaning operation.
3.
Adjust the installation brackets so that the screws are set to 3/16” deep. Attached the brackets to the
piezoelectric sensor using cable ties or tie wire. Use all 7 supplied brackets, spaced evenly over the
length of the sensor.
4.
Lower the piezoelectric sensor and the lead-in cable into the roadway slot to ensure proper fit. The
upper surface of the sensor must be 5/16” below the surface of the roadway. The distance must be
maintained primarily in the wheel paths of the road. After proper clearance is obtained, pull the cable
ties tight so that the sensor is snug to the screw of the installation bracket and carefully remove the
sensor from the slot.
5.
Prepare the grouting material according to the manufacturer’s specification. Fill the slot one half (½)
full to tack the sensor in place. Before the sensor is placed in slot, it is crucial that voids are kept to a
minimum by using a putty knife to quickly press the grout against the sides of the slot. Grout is not to be
poured into the slot for the lead-in cable. Use loop sealant or duct seal to plug the flow of grout into the
lead-in cable slot.
6.
Set the Piezoelectric sensor into the grout while gently moving it back and forth to reduce the voids
underneath the sensor. Allow 10-15 minutes for the grout to partially cure. The sensor should not
move, held firmly in place by the grout.
7.
Remove the installation brackets by cutting cable ties or tie-wire. Trim back the cable ties below the
surface of the road.
8.
Prepare grouting materials to fill up the remainder of the sensor slot. Pour grout evenly through out the
sensor slot, up to the top covering the sensor completely, following the contour of the road surface.
Allow the resin to fully cure (30-40 min.) and grind off any excess materials flush with the road using an
angle grinder or belt sander. Do not over grind. Remove any excess grout from the roadway around the
sensors to prevent any bump when driving over the sensors.
9.
Complete the installation by filling the lead in cable slot with loop sealant materials. A thin walled
plastic tubing (minimum 3/8” ID flexible PVC or polyethylene) will contain the lead-in cable. In the
unlikely event that the sensor needs to be replaced, the lead in cable can then be pulled through the
tubing.
10. When the cable is routed all the way into the cabinet, cut the cables to the final length and install the
BNC connectors. Again, check the resistance and voltage output using a digital multimeter. The
resistance should be infinity and voltage deflection should be observed as truck passes over the sensor.
Record all results.
TESTING
The provisions of Section 701.16 shall apply, unless otherwise stated below.
The contractor is responsible for recording data and preparing the report of test results.
For work having been reported completed by the Contractor, any measurements not consistent with the
equipment manufacturer’s operational requirements or that of the Resident Engineer’s findings shall be corrected at the
Contractor’s expense.
The Contractor shall be responsible for recording data for each of the above tests and providing a completed
report to the Resident Engineer.
LOOP DETECTOR
23
The contractor shall provide a loop inductance meter to perform the inductance tests. If the loop inductance
does not conform to the traffic monitoring equipment manufacturer’s requirements, the number of turns of wire in the
trench shall be adjusted and the inductance of the loop shall be re-tested at the contractor’s expense. All measurements
shall be made at the detector unit location, with loop field-connected to lead-in cables and detector units disconnected.
The Contractor shall perform the following tests:
Loop Inductance
Resistance (Continuity)
Leakage Resistance to ground and other conductors
Change of inductance when a vehicle drives over the loop
TESTING PIEZOELECTRIC SENSORS:
The piezoelectric sensors should be tested prior to and after installation. The contractor shall provide an
LCR meter, such as a BK Instruments 875A or 875B to perform the following tests. These tests should be done
prior to installation:
1. Capacitance - measure the capacitance of the sensor with the attached lead in cable
2. Dissipation Factor – should be less than 0.04
3. Resistance – measure the resistance across the sensor.
Readings should be within the manufacturer’s current specification for the product.
Once the sensor is installed and the grout has cured, retest the sensor according to the instruction above.
On Site Calibration: When calibration is required, the vendor shall calibrate the WIM system after
successful installation and testing. An NJDOT Bureau of Transportation Data Development (BTDD) representative
shall witness and approve the testing and calibration of the completed system. The contractor shall notify NJDOT
BTDD (Brian Britton 609-530-3478) 7 days in advance of the scheduled dates for installation, testing and
calibration.
Each weight sensor shall meet the following accuracy criteria:
Mean Error
Standard Deviation
Speed
+/- 1 MPH
+/- 2 MPH
Axle spacing
+/- 2 in
+/- 3 in
Vehicle Length
+/- 12 in
+/- 18 in
Gross Vehicle Weight
+/- 5%
+/- 8%
Steering Axle
+/- 10%
+/- 10%
The above accuracy specification shall be based on a testing program as defined in ASTM Standard E1318
for type 1 WIM equipment.
Test unit for Calibration Loading: The contractor will provide a loaded, pre-weighed, and measured test
vehicle that will make multiple runs over the WIM-system sensors in each lane at prescribed speeds. The test
vehicle shall be a five axle tractor-trailer combination truck with good suspension, preferably air, with a nonshifting load (approximately symmetric side to side load) to a weight of between 75,000 to 80,000 pounds, gross
vehicle weight (GVW). Ensure that the truck is in excellent mechanical condition and the tires are dynamically
balanced and inflated to recommended pressures. The contractor shall provide documentation of the weight (Front
axle and GVW) from certified static scales. At least 10 runs per lane shall be made before adjustments to the
calibration factors and 3 more runs after the adjustment with value meeting the tolerance listed above. Each sensor
will be calibrated independently from each other in each lane. Record all calibration data from each run and submit
a copy to BTDD personnel.
Before Calibration: The following steps are involved in the on-site calibration process for each
instrumented lane:
1. Adjust all WIM-system settings to the manufacturer’s specification or the vendor’s recommendations
(vendor’s representative must be certified and experienced in the type of system being
calibrated).
24
2.
Using a calibrated radar speed meter, take sample speed readings from an average of 10 vehicles each
lane and adjust the WIM system settings accordingly.
Acceptance Test for New Traffic Monitoring Systems.
For new sites or sites with newly installed sensors, the Department will take ownership of the site only
upon successful completion of the acceptance test. All sensors have to be tested in accordance with the testing
procedure above, with-in limit specified above or by the manufacturer. For WIM sites, no calibration will be
scheduled until all test results had been reviewed by the Bureau of Transportation Data Development (BTDD)
Representative. (Call Brian Britton at (609) 530-5379). Acceptance test will start after the successful calibration.
The AVC, and the ATR system should operate continuously for 21 consecutive days recording and storing data.
The AVC and ATR stations should record traffic data correctly to be witnessed by BTDD staff at the beginning and
end of the 21 day test period. Collected data will then be processed and analyzed for reasonableness. Failure of
the system furnished by the contractor/vendor will cause for the acceptance test to be repeated after problems have
been corrected.
EXCAVATION AND BACKFILL
Excavation and Backfill. The provisions of Section 701.06 shall apply, unless otherwise stated below.
The item “Piezoelectric Axle Sensor Removal” shall consist of removal of the complete axle sensor,
