California transportation
officials are scrambling for answers after the twice-postponed
bid opening for the innovative suspension span of the $2.6-billion
San Francisco-Oakland Bay Bridge attracted just one bid that
came in double the $740-million estimate. Record steel prices
are a key factor in the huge differential, but the spans
unique design, tough schedule and strict specifications ratcheted
up bidding contingencies, sources say. Others point to likely
flaws in developing and communicating the engineers
estimate.
The sole bid was offered May 26
by a joint venture of American Bridge Co., Coraopolis, Pa.;
Nippon Steel Bridge, Tokyo; and Fluor Enterprises, Aliso Viejo,
Calif. The teams $1.4-billion bid represents use of
foreign-supplied steel. Its proposal also includes a $1.8-billion
bid using domestic steel. Buy American provisions
were waived because the price reflecting foreign steel is
more than 25% lower than the domestic price, says Dan McElhinney,
deputy district director for the California Dept. of Transportation
in Oakland.
We hope they award it,
says Michael Cegelis, senior vice president of American Bridge,
the teams lead firm. It represents a tremendous
amount of effort in the last 16 months, and its by far
the most weve ever spent on a bid. Cagelis would
not elaborate, but sources say that cost may be as high as
$5 million.
Caltrans pushed back the initial
bid date in October to allow teams to include both foreign
and domestic steel in bids (ENR 11/3/03 p. 10). The bid date
had already been postponed once, from October 2003 to January.
Caltrans also extended the construction schedule by 15 months
and modified the price formula, permitting teams to bid on
time as well as labor and materials. The 1,860-ft-long spans
innovative design, by San Francisco-based T.Y. Lin International
in joint venture with Moffatt & Nichol, Long Beach, Calif.,
will have a single-tower, self-anchored span. Among other
unusual features, design calls for parallel 25-m-wide, hollow
orthrotropic steel boxes.
Caltrans
expected bids from two joint ventures and possibly a third,
McElhinney says. Im surprised we got a single
bid, adds Randy Rentschler, spokesman for the Metropolitan
Transportation Commission, an Oakland regional agency and
one of the projects funders. I do not know why
the contractors were on the sidelines on this project.
Sources close to the bidding say
a joint venture of Peter Kiewit Sons Inc., Omaha, and
Skanska Inc., Whitestone, N.Y., was another contender as late
as one month before the bid opening, but it did not ultimately
bid. We were interested, says Bruce Grewcock,
Peter Kiewit chief operating officer. But we dont
comment on why we bid or dont bid a job. Kiewit
itself was the sole bidder for an earlier bridge foundation
contract last year, which came in 63% over estimate (ENR 11/3/03
p. 10). The firm won the job in a rebid, with a significantly
lower figure.
Bidding executives point to the
gyrating steel market for a structure whose unique design
and construction specs could require as much as 100 million
lb of permanent steel and another 40 million lb of temporary
steel falsework, says Cagelis. Individual pieces get
very large, he notes. You have to do it perfect
the first time.
The 40 to 60% increase in steel
prices nationally in the first quarter of 2004 became an issue
only after bids had already been postponed, McElhinney says.
Its really the climb since December that is definitely
a factor in this bid, he says. Caltrans...
