MDOT To Delay Bids on Bridges
Design-Build Method Leaves Many Unknowns

MDOT will delay receiving and opening bids
for the rebuilding of the Biloxi-Ocean Springs and Bay St. Louis Bridges
for at least two weeks. The delay was confirmed Tuesday afternoon in an
interview with MDOT's David Foster, assistant chief engineer for
pre-construction.
Foster says that MDOT still does not have
the money to rebuild the bridges that were largely destroyed by Hurricane
Katrina four months ago. He says that the delay in Washington over the
Katrina relief package is partly responsible, but they also want to give
the list of bidders more time to prepare their proposals. Six companies
have been selected for a short list of bidders for the two projects, three
for each bridge.
The money issue, however, should be
resolved with the Senate Passage of the $29-Billion Katrin relief bill
Wednesday night. That bill contains
$740 million to repair
Mississippi’s roads and bridges.
MDOT had announced that they wanted to
received bids by the end of the month, and open bids January 9. But now
the awarding of the bids will not be until late in January.
Meanwhile, MDOT's plan to use the
Design-Build method of construction means that the agency doesn't have any
specifics as to what the bridges will actually look like. Foster says that
they are providing fairly rudimentary requirements such as lanes, height
and where the bridges are to be located. He says that the contractors will
submit proposals as to the designs and esthetics later.
Bridges are often used to establish a
certain theme or esthetic to a city, such as what the Golden Gate bridge
does for San Francisco, but Foster says a suspension bridge is not
feasible and is too expensive. Still, he says the contractors will be
judged partially on their esthetic design.
Foster says that the design for the
Biloxi-Ocean Springs bridge will include replacing the bridge over the
railroad track in Ocean Springs and will have a terminus just east of
McElroy's Seafood Restaurant. He also said that the curve on the west side
near Biloxi will be reduced. Both bridges, in Biloxi and Bay St. Louis,
will have a pedestrian walkway on land under the bridges for people to
cross to the other side.
There remains a considerable number of
questions over how the bridges will be paid for. MDOT is notorious for
promising bridges and roads, then failing to deliver on time. The
Cowan-Lorraine Road is a good example, which was delayed for years. There
are also questions regarding the Design-Build method that MDOT is using
for the first time.
Design-Build sharply cuts the traditional
oversight that protects the public's interest regarding poor construction
and fraud. MDOT insists that it has thought this through, but this will be
the first time MDOT has ever used this method to build anything in the
state. Foster says that it will save MDOT time as the bridges will be
built as they are designed. Essentially, the contractor will begin
construction BEFORE they have their plans finalized.
GCN asked if this would create a situation
that the contractor will not know what is true costs are and numerous and
costly change orders would result. Foster said that a change order process
will be part of the contract.
GCN also asked why the bids have not been
received before the money was finalized as it seems that the contractor
could just bid to match the available money. Foster said that MDOT has a
rough cost estimate based upon its experience and that the estimated
$200-million price for each bridge could come in just under those amounts.
Still, Foster says MDOT has no experience with Design-Build contracts,
though he said Florida frequently uses that method.
GCN asked Foster if he knew if Florida
used the Design-Build method for bridge construction, and Foster said he
did not know. But he explained that the Design-Build system should save
time over the conventional design-bid-build process that is the
traditional method.
"Design bid is not low bid, but best
value" said Foster. "With the Design-Bid-Build method it would take us at
least eight months (to design the bridge). With the Design-Build method,
your plans continue to be updated as you come out of the ground."
GCN is concerned that the state is setting
a situation up that could actually delay the completion of the bridges due
to unexpected costs or design problems stemming from a project that is
engineered as it is built. Foster said he thought his agency could handle
those issues.
"The contractors assume the liability and
safety," Foster said.
