Watermark Kendall East at 250 Kendall Street
Scope/Solutions
Watermark Kendall East brings an additional 144 apartments to a new residential complex, which also includes a 321-unit tower and parking structure constructed in an earlier phase. The two buildings share a retail podium and many amenities, while remaining aesthetically independent. The east building’s elevation, with its punched curtain wall and metal panels, complements the west tower’s combination of curtain walls and punched windows. SGH consulted on the building enclosure.
SGH assisted with the design of the building enclosure, including the punched glass and aluminum curtain wall, windows and terrace doors, wall and plaza waterproofing, and roofing. Highlights of our work include the following:
- Reviewed the building enclosure design and recommended modifications to improve the performance
- Consulted on the design for 30 ft tall flanged punched windows fabricated from curtail wall components
- Developed details to integrate the various systems, including the transition between the new plaza waterproofing to the existing system at Watermark Kendall West
- Designed complex expansion joint details around separations between the many structures
- Reviewed related contractor submittals to compare with the design intent
- Performed water testing at select curtain wall areas and terrace doors during construction to compare with the project’s performance requirements

75 State Street
The use of gold leaf in Boston dates back nearly 300 years. This material, however, was untried and unproven on a large scale for modern buildings until the construction of 75 State Street in the late 1980s. SGH evaluated the technology and its applicability to the granite for the building.
