Superstorm Sandy Rehabilitation for MTA’s Montague Tunnel

Highlights:

  • Delivered ahead of schedule
  • 24/7 accelerated work schedule
  • 14 month tunnel closure

The Montague Tunnel, which connects the “R” line between Brooklyn and Manhattan, was flooded during Superstorm Sandy causing extensive damage to the tunnel’s vital signal and power systems. The Metropolitan Transportation Authority (MTA) closed the tunnel and selected a tri-venture team, Judlau Contracting, TC Electric, LLC., and J-Track LLC, to repair the tunnel and replace track components and electrical systems. The project was completed on an accelerated 24/7 schedule. Scope of work included the construction of new duct banks, construction of circuit breaker houses, power and communications, structural rehabilitation, track rehabilitation, lighting, and full replacement of communications, substation components, emergency systems, and other assets.

Rehabilitation of the Culver Line Viaduct Phase II

Highlights:

  • Delivered 2 months ahead of schedule
  • 45 month accelerated project timeline
  • No major disruptions to train service

The Metropolitan Transportation Authority’s (MTA) old Culver Line viaduct, which supports the F subway line, first opened in the 1930s and needed to be replaced. The goal of the project was to rehabilitate the concrete viaduct deck by removing existing track, performing signal work and installing cables within the viaduct to allow repair and rehabilitation of the existing concrete deck. The MTA selected the Judlau Contracting, and TC Electric LLC, joint venture for the project.

Upon starting the work, it became apparent that the deterioration of the concrete structure was far greater than anticipated, which posed serious safety risks and potential project delays. Judlau worked together with the MTA to expedite the critical repairs without any major disruption to train service. The JV team also completed a significant amount of signal work, including the replacement of signal switches, installation of new interlocking, relays, and other components. A new signal relay room and central instrument room were also built.
