Project Summary

Scope/Solutions

The first phase of the eighteen-acre development in Tyson’s Corner includes four new buildings and a shared podium, which extends two levels below grade. The buildings house 750 apartments, 400,000 sq ft of office space, more than 200,000 sq ft of retail space, a new flagship grocery store, and a movie theater. SGH consulted on the building enclosure design for all four buildings and the podium.

SGH consulted on the design of the building enclosure, including below- and above-grade waterproofing for the podium, window walls, architectural precast concrete wall panels, brick masonry cladding, waterproofing at the amenity deck, and roofing. Highlights of our work include the following:

Reviewed the proposed design, recommended ways to improve performance, and developed details to integrate the enclosure systems
Performed studies to help the project team with their selection of cladding materials
Helped the project team understand key considerations related to mitigating staining and discoloration of architectural precast concrete wall panels
Collaborated with the design team to evaluate fenestration systems and their effect on the overall enclosure design
Coordinated building drift under lateral loads with the enclosure design
Participated in a large-scale mockup program to evaluate the performance of the window walls, as well as the detailing and constructability of the facade
Performed construction-phase services, including reviewing submittals, visiting the site to observe ongoing work, and helping the construction team address field conditions
