Warnings Prove Prescient as Chinese Welding Issues Delay Bay Bridge

July 31, 2009 from the National Steel Bridge Alliance

Welding problems at the China-based steel fabricator for the San Francisco-Oakland Bay Bridge have caused a two-month delay in shipping the pieces to the Bay Area, according to Steve Heminger, executive director of the Metropolitan Transportation Commission and a member of the panel that oversees bridge construction.

"Bay Area transportation officials are concerned that the delayed steel delivery could push back the completion of the $6.3 billion eastern span, which is now scheduled to open in 2013," according reports in the San Francisco Chronicle.

Back in 2004, the National Steel Bridge Alliance cautioned about circumventing the Buy America bridge provisions and using a Chinese fabricator for this project. The issue developed when the single American bid for the project was higher than expected. But rather than using a value engineering process to optimize the design and decrease costs, it was decided to use a China-based fabricator and Chinese-produced steel. At the time, NSBA officials stated: "It could be redesigned more economically with a U.S.-based collaborative effort." It now appears the result of rejecting that option will be increased costs and substantial delays in project completion.

The welding issues on the steel were first discovered last year but
Caltrans and the Metropolitan Transportation Commission thought the
issue had been resolved; instead, it now appears the problems are even
more serious than originally thought. As a result of finding these new
problems, Heminger, incoming Caltrans Director Randell Iwasaki, and
Bimla Rhinehart, executive director of the state Transportation
Commission, plan to head to China to press their concerns with
officials from the steel fabricator and project contractor. As
commission spokesman Randy Rentschler explained: "There’s nothing like
intimate, on-the-ground management to solve problems." And of course,
the process would be even simpler if the contractor wasn’t located
6,165 miles from the job site.

The welding issues are not the only problems that have occurred with
Chinese construction products in the recent past. Last year, rumors
surfaced of issues with welds on Chinese hollow structural sections.
The rumors were substantial enough that many warehouses stopped
stocking Chinese tubes and fabricators with Chinese inventory increased
their inspection procedures. Also, the residential construction
industry has been hard hit with lawsuits over faulty Chinese drywall
which may have been used in as many as 100,000 homes in the United
States.

About the National Steel Bridge Alliance

About the NSBA: The National Steel Bridge Alliance (NSBA) is dedicated
to advancing the state-of-the-art of steel bridge design and
construction. This national, non-profit organization is a unified voice
representing the entire steel bridge community. In addition to
structural steel fabricators and producers, NSBA brings together the
agencies and groups who have a stake in the success of steel bridge
construction, including representatives from AASHTO, FHWA, state DOTs,
bridge consultants, erectors, and representatives of the coatings,
fastener, and welding industries. The NSBA’s mission is to establish
steel as the material of choice for bridges and the NSBA’s goal is to
increase steel’s share of the bridge market.
