New York Metropolitan Transportation Authority has awarded two design-build contracts within LIRR double track project
The first contract awarded is to design and construct a total of 12 km of track between Farmingdale and Central Islip. The contract has been awarded to Skanska-Posillico II Joint Venture, and is valued at up to USD 59.7 million. The joint venture will design and build 9.8 km of trackbed between Farmingdale and Deer Park, and 2 km of trackbed between Brentwood and Central Islip. Under the Design-Build Contract for Phase 1 previously approved by the MTA Board, the civil work is nearing completion on 8.3 km of the second track between Ronkonkoma and west of Central Islip. As a result, the project will add a total of 20 km of track to an existing 8.7 km of track, creating an 29 km-stretch of double track.
The second contract is to design and build a new signaling system that will use computer-based train control software to better coordinate train movement when the second track is activated. The contract has been awarded to Ansaldo STS USA, and is valued at USD 44.8 million. The work will include final design, fabrication, delivery and system integration, and testing of new components, including transmitters and 28 new wayside “huts,” and other infrastructure associated with new interlockings at Farmingdale, Wyandanch, Deer Park, and Central Islip, and a modified interlocking at Ronkonkoma.
Construction work on the double track project is already in progress. By the time the entire project is completed, the LIRR estimates double track will have injected close to USD 100 million into the Long Island economy.
Double track is one of seven major LIRR construction projects that will improve service and reliability on the LIRR’s Ronkonkoma Branch.
