The MTA's East Side Access Project is a multi-billion dollar infrastructure project designed to bring Long Island Railroad to Grand Central Station in New York City. Contract CM006 (the Manhattan North Structures Package) involves the installation of permanent structural concrete lining and fit-outs within tunnels, caverns, and interior structures. The existing tunnels run from just north of Grand Central Terminal located in Manhattan to Long Island City, Queens. CM006 also includes the rehabilitation of the 63rd Street Tunnel and construction of the 63rd Street Tunnel duct bench.

Concrete/Shotcrete Applications

The project consisted of approximately 1,300 individual, reinforced-concrete or shotcrete pours/applications. These concrete placements encompass:
  • 10,051 ft. of tunnel arch
  • 7,140 ft. of tunnel invert
  • (3) caverns (including various wyes, cross-overs, inverts, walls, and arches)
  • (2) multi-level ventilation structures (walls, elevated slabs, connecting tunnels, adits, and arches)
  • (6) cross passages
  • 15,600 ft. of concrete duct benches
  • 1,000,000 ft² of waterproofing membrane installation

63rd Street Tunnel Rehabilitation

The existing 63rd street tunnel was originally constructed in the late 1970s. The rehabilitation work within this tunnel consisted of:
  • Concrete Spall Repair
  • Lead Abatement
  • Asbestos Abatement
  • Drainage
  • Invert Repairs
