Grand Central Terminal located in one of the most crowded sections of Manhattan, is always a challenging space to work in. One of our most recent renovations involved inserting 2 floors above Vanderbilt Hall for the upgrade of the Employees Facility. The 3rd floor slab over Vanderbilt Hall is constructed of terra cotta and steel beams. There are over 36 feet of empty vertical spaces between the 3rd floor and the 6th floor. In this area, we inserted the 4th and 5th floors.
The steel entered the building through the landmark windows which were removed, was loaded onto fabricated trolleys and traveled across a timber flooring to their position where they were lifted and bolted to the appropriate connection. The steel was designed as a composite using a long span deck. A catwalk hangs from the existing 6th floor steel to bridge the east and west wings of the 5th floor.
A tennis court was also designed on the new 5th floor to accommodate private clients.
