Sustainability case study
Skanska Koch was awarded a $189 million subcontract to supply and erect 24,000 tons of structural steel for the Transbay Transit Center, the new multi-modal transit hub in downtown San Francisco.
The project included the removal of the access trestle above the lower concourse level. The project included the shop fabrication, shipping, erection, bolting up, and welding of the steel framed structure. Due to the height and size of the building, the erection and sequence was constructed by bay by bay from bottom to top with a crawler crane on a trestle. The project also included the assembly of cast steel nodes for basket columns and the installation of steel decking throughout the project.
The Transbay Project, the largest transit project in the Western United States, has been nicknamed the “Grand Central Station of the West” and will house 11 transit systems under one roof when it is completed.
