design/build team delivered this project on a fast-tracked schedule while working with multiple agencies and stakeholders, each with specific program requirements. Using a formal partnering charter, the team maintained a high level of communi- cation to clearly communicate program changes and milestones to all team members. Faced with SFO’s desire for

an iconic building and the strict requirements of the FAA for a high- performing Airport Traffic Control Tower, the team worked together to create a design that would meet the

including several design changes, the team maintained the budget and schedule and delivered a project on target to receive LEED Gold certification.

Meeting the Challenge of the Difficult Job – Heavy Engineering Constructor Winner: Shimmick

Construction Co., Inc. for “Transbay Transit Center, Below Grade Concrete Package” – San Francisco

Te new Transbay Transit Center in

bustling downtown San Francisco will be the city’s new transit hub, ultimately serving BART, MUNI, commuter bus services, Caltrain and high speed rail trains. Stretching four city blocks long and one block wide, the jobsite is surrounded by skyscrapers and residential towers. Tis high profile, high hazard setting is where Shimmick Construction Company successfully completed the $124 million below

year project duration, Shimmick worked with owner, the Transbay Joint Powers Authority, and multiple prime contractors who were building other portions of the project to mitigate and overcome a host of challenges. Safety, creativity and teamwork proved key to their success. Major project challenges stemmed

from the need to orchestrate the construction work up and around a temporary access trestle, within an extremely restricted site in the heart of San Francisco, all while constantly coordinating workflow around that of other prime and trade contractors. Each stage of construction posed

unique issues. For example, the team had to overcome major access during construction of the mat foundation slab. Because it is 60 feet below the access trestle at street level, this work was supported almost exclusively by cranes staged on the trestle, requiring extensive planning and coordination. Te project’s accelerated schedule

also was challenging. To make up time, Shimmick had to “double head” work from the middle of the project rather than working from the west end to the east. Tat approach caused a heavy stacking of trades and minimal working areas that demanded constant coordination and logistics scheduling. Shimmick Construction’s proactive,

solution oriented approach led to the successful, on time completion of the Transbay Transit Center’s Below Grade Concrete Package in November of 2015.
