Award: Subway extension
Value: $1.02 billion
Location: New York City
Client: Metropolitan Transit Authority
A joint venture of three major construction firms will provide design-build services on a $1.02 billion subway extension project in New York City.
The Metropolitan Transportation Authority selected Skanska, Traylor Bros and Walsh Construction for Phase II of the Second Avenue Subway Project, according to a Monday announcement from Stockholm-based Skanska.
The transit project will extend the Q line into Harlem and East Harlem and add new stations at 106th Street and 116th Street on Second Avenue. A terminal station at 125th Street and Lexington Avenue will serve as a transfer point to the 4/5/6 lines and Metro-North.
When finished, the Second Avenue Subway will have a continuous, two-track corridor from 125th Street to Lower Manhattan.
Project scope includes:
- Designing and constructing new subway station structural shells between 105th Street and 110th Street for a future station at 106th Street.
- Constructing the structural tie-ins to existing tunnels.
- Supporting excavation and earthwork.
- Installing roadway decking to maintain existing traffic.
- Building at- and below-grade structures for two station entrances.
- Utility support and reconstruction.
Design services for Phase II will be led by London-headquartered engineering firm Mott MacDonald.
This isn’t the first ride for the trio of Skanska, Evansville, Indiana-based Traylor and Chicago-based Walsh. The joint venture partners won another megaproject, the $1.29 billion design-bid-build contract on the Hudson Tunnel, in April.
Skanska’s share of the contract is worth $498 million, according to the firm. The contractor previously built Phase I of the project with JV partners J.F. Shea Construction, based in Walnut, California, and Schiavone Construction out of Secaucus, New Jersey. That phase, delivered in 2017, extended service from 63rd Street to 96th Street.
Skanska has racked up rail infrastructure wins in and around the Big Apple. Last month, Penn Transportation Partners, a team of Halmar and Skanska, won the master developer role for the $8 billion renovation of Penn Station.
Construction of Phase II is expected to reach substantial completion in the third quarter of 2030, per Skanska’s release.
