330 Madison Avenue

New York, NY

GMS provided façade and structural consulting services to the owner for overcladding this 1960s vintage Midtown office building with an entirely new aluminum and glass curtain wall.  The work was performed while the building was completely occupied.  The new façade, while increasing the percentage of daylight openings, brings the building into compliance with the 2009 New York State Energy Conservation Construction Code.

GMS also provided structural consulting and special inspection services for other projects associated with the $100 million overhaul, including new window washing rig, new generator, upgraded MEP systems, new lobby, a structural study of building setback roofs to assess the basic design capacity and tenant renovations at the office and ground floor retail areas.
