Construction completes at 40-storey office tower in Manhattan
Multidisciplinary engineering and consulting firm Arup, in partnership with design practice Skidmore Owings and Merrill LLP, has completed the structure and envelope for a 1000,000 square feet office tower development in Manhattan.
Located in the heart of Manhattan at 250 West 55th Street, the 40-storey tower features office space, a green roof, two podium levels, and two basement levels.
Designed to achieve LEED Gold certification, the building has incorporated viscous damping system into the outrigger and belt truss at the crown of the building. This damping system reduces the building's motion during wind storms, and enabled the steel tonnage to be reduced by 10%, which saves $5 million in costs.
Providing more usable space per floor, seven small viscous dampers have been integrated into the mechanical space at the top of the building. It preserves valuable space within the building that would have otherwise been occupied by a tuned-mass damper, thereby maximising rentable space for the landlord, Boston Properties.
The tower is slated for occupancy in early 2014.
