| Abstract: |
The design and construction of the Gerald Desmond Bridge Replacement brings many firsts and innovations to California’s infrastructure landscape. Preliminary engineering studies carried out for this design-build project resulted in a 305-meter cable-stayed main span bridge, 157-meter tall mono-pole towers, and single and double-celled box girder approaches built on a moveable scaffolding system. This paper reviews some of the innovations of the winning proposal design: approach viaduct optimization, viaduct frame dynamic response balancing and tower geometry conception. The focus of the review is interaction between design and construction teams in project innovation. The review concludes that while project innovation is best served by healthy communication between design and construction teams at the preliminary engineering phase, the most challenging innovations benefit from healthy communication maintained through execution. This way mutual constraints and objectives are conceptually recognized by the innovation, while unknown obstacles associated with executing a new idea may be addressed expediently with the collective design and construction skill set. |
