MTA-LIRR Design-Build Services for the New Second Track on Main Line Ronkonkoma Branch, Phase II

Jan 2, 2024 | News and Awards

Design-Build contract to construct a second track from Central Islip to Farmingdale Station. The Skanska-Posillico Joint Venture teamed with WSP Parsons Brinkerhoff to carry out the project design work and The LiRo Group to perform professional engineering inspection on the project. Construction included the building of retaining walls and grading for track bed, and installation of cable troughs for the placement of LIRR signal cables and wiring. Means and methods used for this project allowed work to occur near the existing rail line, did not compromise the structural stability of the existing rail infrastructure, worked within the LIRR force account schedule, and prevented any track fouling or interruption to train service. The team’s proactive partnership with third parties was key in establishing direct and effective communication lines with utility owners in the LIRR corridor.
