New York, NY

Four Seasons


Designed by I.M. Pei & Partners and Frank Williams & Associates, the Four Seasons has 368 guestrooms on 52 floors. The hotel, constructed in 1992, features limestone-clad precast concrete panels; aluminum-framed casement windows at guest rooms; and bronze-framed curtain walls, storefronts, and canopies. The building has multiple setbacks creating terraces with brick- and stone-clad parapets and metal railings. SGH has worked on several building enclosure assessment and repair projects at the hotel.

SGH performed condition assessments, including Facade Inspection & Safety Program examinations as required by the City of New York, and designed repairs for the hotel. Highlights of our work include:

  • Visually surveying the existing building enclosure systems, including below-grade spaces, terraces, roofing, and exterior walls
  • Performing water testing on windows, doors, terraces, and the roof
  • Providing conceptual remedial options to address water leakage at windows and doors
  • Designing emergency repairs at terraces and the roof
  • Preparing construction documents for facade repairs and providing bid and construction phase services
  • Collaborating with the owner and contractor to identify means of accessing the facade while minimizing disruption to hotel operations
