Purple Line Extension 3 Design-Build Stations

As the last part of the transformative $9.3 billion Los Angeles County Metropolitan Transportation Authority (Metro) Purple Line Extension Project, Section 3 runs 2.56-miles between the future Century City/Constellation Station site in the Century City neighborhood, to a new station on the southwest corner of the UCLA campus, then west under I-405, terminating at another new station at the U.S. Department of Veterans Affair property in Westwood.

STV, as part of the design-build team led by the Tutor Perini/O&G joint venture, is serving as the lead designer, systems integrator for the Section 3 stations component. STV is responsible for all associated civil, architectural, structural, mechanical, electrical, plumbing, landscape, track and traction power systems design for two new stations at Westwood/UCLA and Westwood/VA Hospital. Both stations will include station entrance portals equipped with stairs, escalators, elevators, and bicycle parking.

For this contract, the firm is also performing all infrastructure design for the traction power, automatic train control, and communications systems, as well as specifications, and selection of tunnel ventilation fans, silencers dampers, and actuators, HVAC units, fire smoke dampers, fire dampers, pumps, and plumbing.

In addition to performing design services for Section 3 tunnels, STV is also performing design services for the Section 3 stations component and is the principal engineering and lead design firm for the 2.59-mile Section 2 of the Metro Purple Line Extension Project.
