Marriott Headquarters 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
