Station Renewal at 138th Street
This client performed the rehabilitation of stairs, platforms and mezzanine at 138th Street Grand Concourse station Jerome Line “A” Division (IRT). This station has two side platforms and three tracks and is the only other station on the line to be built underground. The Rehabilitation of 138th Street Grand Concourse Station included station upgrades and structural repairs of the station that first opened in 1918. The Scope of Work consisted of platform edge replacement, new platform concrete toppings, new rubbing board and new non-slip strip tack tile in addition to extensive structural repairs and leak mitigation by applying chemical grout injections. The majority of these activities were performed during weekend within a narrow 53-hour window, before returning the station back to service. The project achieved platform ADA compliance.
