Tutor-Saliba Receives Project of the Year Award for the Caldecott Tunnel Fourth Bore Project

Tutor Perini Corporation (NYSE: TPC), a leading civil and building construction company, today announced that its subsidiary, Tutor-Saliba Corp., recently received the Project of the Year Award from the California Transportation Foundation for the Caldecott Tunnel Fourth Bore Project. This award recognizes the premier transportation project among projects throughout California. Tutor-Saliba constructed this major project for the California Department of Transportation (Caltrans). Tutor-Saliba is led by Tutor Perini’s Civil Group CEO, Jack Frost.

The Caldecott Tunnel Fourth Bore Project won this award over several other high-profile projects including the San Francisco-Oakland Bay Bridge East Span Seismic Safety Project.

The Caldecott Tunnel Fourth Bore opened to traffic on November 16, 2013, on schedule and under budget, saving motorists on average 10 to 15 minutes of commuting time. The project included the construction of a 3,399-foot long, 41-foot wide, two-lane concrete tunnel on the heavily traveled State Route 24 in Alameda and Contra Costa counties. The project included seven emergency cross passages connecting to the existing third bore, sixteen retaining walls, soundwalls, two electrical substations, a two-story Operations, Maintenance and Control building, and various roadway improvements. The project also featured wide travel lanes, roadway shoulders, bright lighting, emergency exits along the length of the tunnel, and state-of-the-art fire and life safety systems. The tunnel’s incident detection and response systems allow monitoring and response to threats inside the tunnel, including detecting and suppressing fires and other hazards, and provide real-time information to help motorists safely exit in an emergency.
