| Client: | American Bridge/ Fluor Joint Venture |
| Location: | California, USA |
| Completion Date: | 2010 |
| Project Highlights: | Structural and geotechnical design for the temporary works for the $1.4B signature span in San Francisco Bay. |
The San Francisco Oakland Bay Bridge Seismic Project is a highly publicized multi billion dollar bridge replacement and retrofit. Constructed in 1936 the 10, 176 foot San Francisco Bay Bridge, the largest in the world at that time, was considered a marvel of modern engineering. Following the earthquake of 1989, the need for a new bridge that would withstand strong seismic action was established. The new San Francisco-Oakland Bay Bridge, which began construction in 2006, will continue the tradition of engineering excellence with the construction of the signature, record breaking, Self Anchored Suspension Span (SAS). Upon completion of the project (projected for 2013), the San Francisco Oakland Bay Bridge will be the longest single tower self-anchored suspension bridge in the world.
Retained by American Bridge/ Fluor Joint Venture, KCB will provide lead construction engineering services for the Self-Anchored Suspension Span for the San Francisco – Oakland Bay Bridge Seismic Safety Project. KCB will provide both the structural and geotechnical engineering services for the temporary steel structure. The temporary works will support the suspension tower, and the two five lane car decks of the superstructure until the loads can be transferred to the suspension cables during the final phase of construction. The falsework, founded in the deep bay muds, will be designed for seismic and ship impact loads for each stage of construction. KCB has also provided erection staging for the steel box girders and the permanent steel tower.
Services Provided:
- Design and analysis of the foundations for the temporary structure
- Design and analysis of the Temporary Towers and Trusses
- Design and Analysis Orthotropic Box Girders
- Erection staging for the permanent steel suspension tower (T1)
- Construction design, staging and sequencing
