The California Senate provided new details Wednesday about construction lapses on the eastern span of the San Francisco-Oakland Bay Bridge, and raised fresh doubts about the long-term reliability of the $6.4 billion project.
The Senate report, prepared by an outside consultant for the Committee on Transportation and Housing, offers background for a Friday hearing to examine allegations of lapses in quality control during a push to complete a structure running years behind schedule and billions over budget.
Among the reports key revelations:
Quality control managers found thousands of cracks in welds produced by a Chinese contractor for the spans signature tower and roadway. Rather than ordering all needed fixes, top California Department of Transportation managers replaced those who discovered the problems.
