T.Y. Lin International (TYLI), as managing partner in a joint venture, provided Consultant Construction Management (CCM) services to New York City Transit (NYCT) for the Rehabilitation of the Cranberry Tunnel, located between Manhattan and Brooklyn and serving the A and C subways. The tunnel was damaged by the tidal surge during Superstorm Sandy. The team provided management of the constructability review, pre-construction, construction, and close-out phases of the project.

Rehabilitation work included repair of facilities, such as fan plants, circuit breaker houses, electrical substations, and pump houses. The scope featured the repair of walls, roofs, and other structural components, as well as electrical, mechanical and plumbing equipment damaged by saltwater during flooding.

Other work included the installation of resiliency products, including flood-proof doors, waterproof caulking, and protective coatings. The project also encompassed the rehabilitation of the structure and components of the 7,117-foot Cranberry Tunnel, including walls, tracks, electrical equipment, third rail, switches, duct banks, and communications equipment and cables.

Project Highlights:

  • The CCM team performed constructability reviews, provided design solutions, reviewed sequencing, staging and phasing requirements, and provided safety inspections during construction.
  • The constructability review saved NYCT more than $1 million.
  • TYLI assisted NYCT in organizing overnight and weekend General Orders (GOs) shutdowns for inspections.
