Aecom selected by TJPA for Downtown Rail Extension project

AECOM and the Portal Connectors team, has been selected by the Transbay Joint Powers Authority, or TJPA, to provide program management and construction management services for the Downtown Rail Extension , or DTX, project, also known as the Portal. The tunneling and station megaproject will extend Caltrain service from its current terminal at Fourth and King Streets to the Salesforce Transit Center and accommodate future California High-Speed Rail service. Once complete, the extension will serve as a key regional rail connection with a combined average ridership forecast of 90,000 daily riders connecting with 11 Bay area transit systems. Portal Connectors, a team led by AECOM, will be responsible for implementing an operating model to successfully deliver an array of program management and project supervision services in support of the Portal. The 1.3-mile rail extension is expected to be constructed principally below grade using cut-and-cover and mined tunneling methods underneath Townsend and Second Streets. The project includes an underground station at Fourth and Townsend Streets along with the Salesforce Transit Center’s basement levels, utility relocation, track and systems work. The Portal is the second phase of the TJPA’s $12B Transbay Program. The first phase replaced the former Transbay Terminal in downtown San Francisco with the modern, multimodal Salesforce Transit Center.
