T.Y. Lin International (TYLI), a globally recognized full-service infrastructure consulting firm, announces that the Construction Management for the Rehabilitation of the Cranberry and Joralemon Tubes Project in New York, New York, was named 2019 Project of the Year for Category 4: Projects Valued at Over $100 Million by the Construction Management Association of America Metro New York/New Jersey Chapter (CMAA Metro NY/NJ). TYLI joined its project partner in accepting the award at the CMAA Metro NY/NJ awards gala on June 14, 2019.
TYLI, in a joint venture with Hatch Mott MacDonald (TYLI | HMM JV), led a Consultant Construction Management team for a complete Rehabilitation of the Cranberry and Joralemon Tubes for New York City Transit (NYCT). As Prime Consultant, the team provided project oversight, project management, resident engineers, office engineers, inspectors, and Safety and Quality Officers.
The Cranberry and Joralemon Tubes connect the boroughs of Manhattan and Brooklyn under the East River and serve the A/C and 4/5 subway lines. Damaged by the tidal surge during Superstorm Sandy in 2012, these important transit tunnels were also in need of resiliency measures to prevent damage from future storms. The projects addressed approximately 15,000 linear feet of tunnel and over a dozen ancillary structures, with work conducted by two general contractors and numerous subcontractors.
“T.Y. Lin International thanks the Construction Management Association of America Metro New York/New Jersey Chapter for selecting this project for the prestigious 2019 Project of the Year award,” said Chandu Bhoraniya, P.E., Vice President of TYLI’s New York City market. “We are very proud of the Construction Management work accomplished for the Rehabilitation of the Cranberry and Joralemon Tubes project for New York City Transit.”
Scope of work included the replacement of conduit and cables for traction power, communications, signals, tunnel lighting, and the pumps that drain the tunnels, as well as the rehabilitation of piping systems to sewers at street level. Equipment was restored and resiliency measures were installed at fan plants, circuit breaker houses, electrical substations, and pump houses. Along with extensive repairs to duct banks along the tracks, fiber optic lines were replaced and spall repairs were made to concrete tunnel liners and roofs. Fire standpipes and all major electrical lines and equipment were also replaced, including traction power components.
TYLI | HMM JV oversaw the two projects simultaneously, which was achieved by orchestrating close to 100 weekend-long track closures in the two tunnels, where outbound and inbound train service was suspended between 10:00 p.m. Friday and 5:00 a.m. Monday. Extensive planning, scheduling, and coordination were required with NYCT operational groups. This included developing stringent safety and fail-safe measures for removing and restoring traction power, deployment of NYCT flag personnel, access and protection teams, and in-house inspectors, and detailed reporting of weekend activities.
