Major contracts awarded for MTA subway, Hudson Tunnel and CHSRA projects

The Metropolitan Transportation Authority has selected a joint venture (JV) of Skanska, Traylor Bros. Inc. and Walsh Construction to deliver design-build services for the $1 billion Phase II Second Avenue Subway project in New York City, which will extend the MTA New York City Transit's Second Avenue Subway (Q Line) to 125th Street. Phase II project scope includes the design and construction of new subway station structural shells for the future 106th Street Station, new tie-ins to existing tunnels and at- and below-grade structures for station entrances, Skanska officials said in a press release. The JV will also support excavation work, install roadway decking and reconstruct utilities. Phase II design services will be led by consulting firm Mott MacDonald. 

The Gateway Development Commission (GDC) awarded a $712 million contract to Skanska Creamer Sanzari NJSA joint venture for the Hudson Tunnel Project construction package three, known as the New Jersey Surface Alignment project. The JV will construct about 1.5 miles of infrastructure between the new passenger-rail tunnel under the Hudson River and existing Northeast Corridor tracks in New Jersey, GDC officials said in a press release. The infrastructure will support future tracks, signals and other railroad systems that will be installed as part of a future construction package. The JV will build 4,170 feet of retaining walls, an embankment, 3,150 feet of viaduct, new access roads, drainage structures, equipment platforms, stairs, and bridges over Secaucus Road and existing freight-rail tracks. Additionally, the JV will relocate utilities and an auxiliary signal power substation.

The California High-Speed Rail Authority (CHSRA) has selected a consortium of Kiewit, Stacey Witbeck and Herzog to install high-speed rail track, overhead contact systems, train control and communications infrastructure for the 119-mile Central Valley segment of guideway. The Central Valley guideway is currently under civil construction, with over 80 miles completed. The segment will connect to the future Merced and Bakersfield extensions; track and systems installation will begin as soon as civil construction is completed on each segment, CHSRA officials said in a press release. CHSRA's recently completed southern railhead facility in Kern County will serve as the staging and distribution hub for rail, concrete ties, ballast and other key components.
