New York, US

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.

The project involved the construction of an innovative 240-foot span platform structure using post-tensioned precast technology, a rarity among commercial construction projects. Brookfield Properties retained Entuitive to design the foundations and platform support beams, and to develop the structural design of the long-span platform.

Challenge

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

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.
