Project Summary

Scope/Solutions

Marriott International owns and operates more than 8,000 hotels across the world and sought to construct a new global headquarters in the national capital region. The campus includes a new hotel, the Marriott Bethesda Downtown; an office tower for the company’s corporate employees; and a public plaza over the shared five-level concrete podium. SGH consulted on the building enclosure for the hotel.

SGH consulted on the design of the hotel’s facades and roofs. Highlights of our work include:

Identifying relevant performance criteria and helping select building enclosure materials and systems
Reviewing the proposed design and recommending ways to improve airtightness, watertightness, thermal and condensation performance, and constructability
Helping select materials and systems for the facades and roofing
Consulting on the facade systems comprising a combination of glazing systems (e.g., window wall and curtain wall) and opaque exterior wall assemblies (e.g., metal panels and stone cladding)
Developing details to tie the facade into the below-grade and grade-level waterproofing systems of the garage and pedestrian plaza designed by others
Evaluating the roofing design for low-slope and vegetative roofing to help develop specifications and ballast detailing
Witnessing testing of laboratory and on-site facade mockups
Providing construction phase services, including reviewing relevant submittals, visiting the site to observe ongoing construction, witnessing performance testing of as-built assemblies, and helping the project team address field conditions
