The Wilson and The Elm, 7272 Wisconsin Avenue

SGH consulted on the design of below-grade waterproofing, facade, and roofing systems. Highlights of our work include the following:

• Reviewing the proposed design for the building enclosure, preparing concept sketches, and helping develop performance specifications
• Consulting on the waterproofing design for the complex below-grade structure that intersects with the underground train station
• Evaluating rainscreen cladding options for the Elm
• Estimating thermal (i.e., u-factor) and solar (i.e., SHGC and VLT) values for the Wilson curtain wall using custom parametric calculation tools and providing these values to the mechanical engineer for their energy model
• Participating in the design-assist process for the Wilson curtain wall
• Reviewing wind tunnel studies and analyzing the protected membrane roofing and terrace assemblies for wind uplift resistance
• Developing details to integrate the many systems, including locations where a skybridge links the two Elm towers; waterproofing for a rooftop pool, water features, bio-retention planters, and numerous terraces; and other facade, roofing, and expansion joints assemblies
• Visiting facade manufacturing facilities to observe and document their quality assurance/quality control procedures
• Witnessing testing of laboratory and on-site facade mockups
• Providing construction phase services, including reviewing relevant submittals, visiting the site to observe ongoing construction, and helping the project team address field conditions
