NEW YORK, NY
Manhattan West Platform
The Manhattan West Platform was the first stage in a commercial development project to reclaim 2.6 acres of land over the busiest commuter rail corridor in North America.
Completed in 2015, the platform serves as the foundation for a plaza and public space over previously uncovered railway tracks and serves part of a new 5.4 million ft² office development in West Manhattan.
The project required constant coordination with Amtrak and the Long Island Railway, and with the design and construction of Amtrak’s new high-speed rail terminal at Moynihan Station, directly east of the site.
Brookfield Properties retained Entuitive to design the foundations and platform support beams, and to develop the structural design of the long-span platform.
The project involved the construction of an innovative 240-foot-span platform structure using post-tensioned precast technology, a rarity among commercial construction projects.

KEY CONSIDERATIONS
Challenge One
It was essential in the design of the platform to minimize, or completely avoid, disruption of rail service to New York’s Penn Station.
Solution One
Entuitive developed a design that incorporated deep post-tensioned segmental precast box girders to span 16 tracks, allowing crews to avoid intrusive construction at track level.
