Westlight

Scope/Solutions

The mayor selected EastBanc’s team to lead the West End’s revitalization and redevelopment of the neighborhood’s library, police special operations building, and fire station. The development includes two parcels: Square 37 at 1111 24th Street NW is the site for Westlight with more than 150 residences over a new public library and retail space and Square 50 includes a new fire station and squash courts with affordable housing above. SGH consulted on the building enclosure design for both projects.

The eleven-story building features a stepped facade, creating many complicated transitions for the building enclosure. SGH assisted with the below-grade waterproofing, glazing, and roofing design. Highlights of our work include the following:

  • Reviewing the proposed design for below-grade waterproofing, aluminum-framed window wall and structural glass curtain wall systems, metal wall panels, low-slope roofs, and waterproofing for the rooftop pool and amenity deck
  • Recommending ways to improve performance and constructability
    Developing details to integrate the various building enclosure systems, including transitions from stepped facades to roofing assemblies
  • Consulting on the design and testing requirements for metal grating and synthetic turf at numerous low-slope roofs
  • Performing hygrothermal and thermal analyses to evaluate moisture performance and heat flow through the proposed wall assembly and at critical building component intersections
  • Consulting on window wall laboratory mockup requirements, including testing and construction
  • Providing construction administration services, including reviewing related submittals, answering contractor requests for information, and observing the as-built enclosure systems to compare with the design intent
