One CitiGroup Headquarters




New York, New York

The One Citi NY project involves the master renovation of two adjacent existing buildings, 388 and 390 Greenwich Street, in order to better combine and unify the buildings as part of a strategy to update the more than 1M square foot CitiGroup corporate headquarters. 

Our team developed security criteria and electronic security systems design including a phased demolition and migration plan for existing security systems and provided construction oversight associated with the renovation. The facility includes additional security elements associated with the data center, trading floors, and emergency operations center.
