Busy Few Weeks
Hurricane Katrina: August 29, 2005, third strongest
ever making U.S. landfall, made landfall in Louisiana in
Plaquemines Parish, near Buras, as a category 3
hurricane with maximum sustained winds of 125 mph
and a minimum central pressure of 920 mb (3rd lowest of
a US land-falling hurricane), after crossing Florida as a
category 1
• Hurricane Rita: September 24, 2005, the fourth
most intense Atlantic hurricane ever recorded, the most
intense tropical cyclone recorded in the Gulf, made
landfall on the Louisiana-Texas border as a category 3
hurricane
Hurricane Katrina
• “the most destructive hurricane
to ever strike the U.S.”
NOAA
• Much work is being
done to provide
safety from
hurricanes to south
Louisiana.
• A question often
asked is why do so
many people live
here?
Why do we live where we do?
Louisiana’s Economy is Concentrated in
the Southern Region of the State
•
•
•
•
73.5 % of state employment
Almost 60% of oil and gas employment
77% of construction employment
67% of all manufacturing employment in
the state.
Every major river must have a port
city near where it meets the sea.
LA DOTD
POPULATED AREA?
• Over 65% of the population of Louisiana lives within
50 miles of the coast (over 2 million according to
2000 census)
OFF SHORE GAS PIPELINES ARE HEAVILY
CONCENTRATED OFF LOUISIANA SHORES AND ARE
SERVICED BY THE TRUCKING INDUSTRY.

hurricane also disrupted operations at the Port of
South Louisiana and the Port of New Orleans…….
Together, these ports account for $150 billion and 20
percent of U.S. import/export cargo traffic annually”

of the Texas ranching industry in the
southeast Texas-southwestern
Louisiana area, from where cattle
raisers drove herds to market in New
Orleans.”

Introduction
• The Louisiana DOTD issues this Request for
Proposal (RFP) to solicit competitive bids for
the emergency repairs to the Interstate 10
bridges (Structure Nos. 4501700001 &
4501700002) over Lake Pontchartrain in
Orleans and St. Tammany Parishes for
damages resulting from Hurricane Katrina in
August of 2005.
Project Location
Caution to Proposers
•
The bulk of the work to be done on this project involves relocating or
resetting 300+ ton monolithic concrete spans. The success or failure of this
project will depend to a large degree on the amount and type of span
moving and setting equipment that can be quickly assigned to the project.
Your work plan should identify the amount, type and location of equipment
that your firm will assign to the project. Key personnel and their resumes
should also be identified.
•
Once bids are opened, the low bidder will be identified. If the low bidder's
work plan identifies sufficient equipment and personnel to be assigned to
the project, the award will be made to the low bidder. If in the opinion of
the LADOTD, the low bidder does not identify sufficient equipment and
personnel, that bid will be rejected and the LADOTD will move to the next
lowest bidder. This process will continue until an acceptable work plan is
identified.
Schedule of Events
• The current schedule of the remaining events that will take
place in the selection process follows this slide. The
LADOTD reserves the right to make changes or alterations to
the schedule as the LADOTD determines is in the best
interests of the public. Proposers will be notified sufficiently
in advance of any changes or alterations in the schedule.
Unless otherwise notified in writing by the LADOTD, the
dates indicated below for submission of items, or for other
actions on the part of a Proposer, shall constitute absolute
deadlines for those activities and failure to fully comply by the
time stated shall cause a Proposer to be disqualified

I-10 Bridges over Lake Pontchartrain
Bridge Nos. 4501700001 & 4501700002
By
September 2-4, 2005
Description of Work
• As a result of Hurricane Katrina, the
LADOTD will need to repair the bridges
carrying I-10 over Lake Pontchartrain. The
Eastbound Bridge is missing 38 spans and
170 spans have shifted in alignment. The
Westbound Bridge is missing 26 spans and
303 spans have shifted alignment. A full
bridge inspection report is available in the
Appendix.
Description of Work
• These spans were constructed in 1963
utilizing monolithic 65 ft. span by 43 ft. wide
(approximate dimensions) systems weighing
approximately 309 tons. The substructures of
both bridges require inspection and may
require repair or replacement as determined
to be necessary. Approach slabs and
roadway must be constructed/repaired to
return facility to service.
Description of Work
• The LADOTD wishes to engage a qualified
and experienced Engineering & Construction
team under a three phase contract to bring the
structures back into service on an emergency
basis. The contract if awarded will be awarded
for Phase 1 only or for Phases 1, 2 and 3 in
their entirety. Should all Phases be awarded,
one contract will be entered into for Phases
1&2 and a separate contract will be entered
into for Phase 3.
Description of Phase 1
• Phase 1: Eastbound structure; realign all
misaligned (undamaged) spans. Lift all
existing undamaged spans off the lake
bottom and replace where possible; when
not possible to retrieve spans from the lake,
remove westbound bridge spans and install
into the eastbound bridge. Provide for safe
two way traffic through completion of
Phase 2. The existing northern crossover
structure may be utilized for this Phase.
Description of Phase 1 Continued
• A new southern roadway crossover structure will be
required to be constructed. The LADOTD wishes to
engage a qualified and experienced Engineering &
Construction team under a three phase contract to
bring the structures back into service on an
emergency basis. The contract if awarded will be
awarded for Phase 1 only or for Phases 1, 2 and 3 in
their entirety. Should all Phases be awarded, one
contract will be entered into for Phases 1&2 and a
separate contract will be entered into for Phase 3.
• Westbound structure; realign all remaining
misaligned (undamaged) spans. Lift all
existing undamaged spans off the lake bottom
and replace where possible; when not possible
to retrieve spans from the lake, incorporate
Acrow bridge panels to provide a safe
structure for one-way traffic.
• Phase 3 will be to return the Eastbound bridge to one
way traffic and an annually renewable contract (up to
3 years after completion of Phase 2) to maintain,
repair or replace the Acrow panel bridge system in
service on the Westbound structure including
removal/salvage of the panels and delivery to a
designated storage yard should the structure be taken
out of service. Also a part of Phase 3 will be
installation and maintenance of all traffic control
striping, signing and barricades required to keep both
directions open and serviceable for safe traffic flow.
Project Information
• Existing data for the project is posted on the
DOTD address
• http://ppms2.dotd.state.la.us/External/01506-0038/acp.html
Bidding
• Bids will be submitted on the bid tabulation
document to be presented to you by noon
today.
• Please review your entire bid document
carefully for all bidding procedures and
requirements.
THE FOLLOWING SLIDES DESCRIBE
THE WORK THAT HAS BEEN DONE
TO REOPEN THE TWIN SPANS TO
FOUR LANES OF TRAFFIC ON A
TEMPORARY BASIS.
Louisiana Approach
Louisiana DOTD prepared full bid
documents (including all permits)
and detailed inspection reports in
9 days and obtained bids from 3
construction firms.
Louisiana Approach
The low bidder was the Louisiana
firm Boh Brothers who bid
$31million vs. DOTD estimate
(using Florida DOT prices from less
than 1 year ago) of $53million.
The inspections reduced the
contractors risk and allowed the
lower bid.
Louisiana Approach
Acrow Bridging
Florida generously offered to loan us an older
design Acrow portable bridging that would only
allow one lane of traffic. DOTD opted to
purchase all new Acrow bridging to allow four
lanes of traffic. The additional cost is expected
to be offset by higher capacity, lower
maintenance cost, and no cost at the end to
return good condition bridge to Florida
Project Information
Data for the project was posted on the
DOTD address shown below (now
requires password).
http://ppms2.dotd.state.la.us/External/0
15-06-0038/acp.html
DOTD feels this information greatly
reduced the bidders project risk and
resulted in a lower cost job.
Total project cost was = $30,964,255.00
(plus ~$4million to return borrowed Acrow bridge to
Florida DOT), increased to ~ $36 million with
additional ACROW.

• WHAT HAPPENED?
– The following illustration is from
DesRoches and Rix at Georgia Tech
– A detailed report was prepared for
design of the replacement bridge by
Moffatt & Nichol along with TRC
Engineers.
HOPEFULL PREVENTATIVE
The truck route restriction caused
by the hurricane is the I-10
westbound over Lake
Pontchartrain. The Chef Menteur
Pass bridge has long been load
restricted.
THE FUTURE
Construction is Underway for a New Interstate 10 Twin Span
Bridge
Now, through the dedicated efforts of its citizens and with
the cooperation of state and federal governments,
construction of a new Twin Span Bridge is underway. The
approximately $800 million project is a testament to the
strength, hope and resiliency of a grand state and strong
nation.
