UPDATED – October 27, 2023 (Request for Qualifications Issuance)

The Transbay Joint Powers Authority (TJPA) is issuing a Request for Qualifications (RFQ) for civil and tunnel design and construction services for The Portal. The TJPA is seeking firms with qualifications and expertise in tunnel design and construction and associated heavy civil work in a dense urban setting. The TJPA intends to procure the services through a highly collaborative progressive design-build (PDB) form of contract to advance detailed design and preconstruction and complete design, construction, and testing and commissioning activities. 

The Portal, also known as the Downtown Rail Extension (DTX) project, will extend Caltrain service from Fourth and King Street to the multimodal Salesforce Transit Center, in the heart of downtown San Francisco and deliver the California High-Speed Rail Authority’s future high-speed rail service to the Bay Area.  It is a transformational, once-in-a-generation investment that will ultimately connect 11 transit systems.
