55 Water Street

Location:New York, NY
Architect:Emery Roth & Sons
Client:Retirement Systmes of Alabama

Once the largest office building in the world and still the largest in New York City in terms of floor space, 55 Water Street was designed by the firm of Emery Roth & Sons. Construction lasted for four years between 1969 and 1972 and spanned four downtown blocks, which were incorporated into a single site and topped with “The Elevated Acre”, one of the city’s largest privately-owned public spaces. It has an advanced infrastructure that includes multiple redundancies in every major operating system from electric, HVAC, and telecom, to life safety and security.

55 Water Street has undergone three separate renovation campaigns, which included repairs to pre-cast panels, caulking of joints with a silicone sealer, replacement of the curtain wall glass and refurbishment of the anodized aluminum curtain wall’s framing members. In response to all eight of the building’s sub-basements being flooded by Hurricane Sandy, a comprehensive program took place in 2012 to address a potential future flooding event. Over a year-long process, Vidaris undertook a comprehensive waterproofing program and was part of the team that planned the flood mitigation program.
