Four Seasons
Scope/Solutions
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

Sleeve Block Testing, Waltham, MA
The unitized curtain wall units for a new high-rise building are fabricated with first anchors and sleeve blocks that attach the curtain wall to anchorage plates cast into the structure. SGH performed the testing to help determine whether the punctured sleeve blocks were structurally adequate.
