The Wilson and The Elm, 7272 Wisconsin Avenue

Scope/Solutions

The mixed-use development at 7272 Wisconsin Avenue includes the Wilson, a twenty-four-story office tower clad in all-glass unitized curtain wall, and the Elm, two thirty-story residential towers clad with window wall and metal panel rainscreen assemblies. The towers share a six-level podium with a landscaped public plaza, retail space, three levels of below-grade parking, and an MDOT Purple Line station that passes through the below-grade structure. SGH consulted on the building enclosure design for the project.

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
