VITA Tysons Corner Center

VITA comprises four below-grade parking levels; three podium levels with parking, lobby, and retail space; and thirty-one residential floors. The building also offers rooftop pool/amenity spaces, pedestrian terraces, and plazas with connections to the nearby Metro station and shopping mall. Highlights of our building enclosure services include:

• Helped develop performance criteria for roofing, cladding, waterproofing, windows, and curtain walls and evaluated material and system options
• Reviewed designs for precast concrete panels and curtain walls and provided recommendations for system detailing and integrating systems
• Consulted on low-sloped roofing at terraces and rooftop areas
• Reviewed proposed designs for grade and plaza levels, including garage lid waterproofing and drainage, integration with the adjacent plaza, and provisions for differential movement between structures
• Provided construction phase services, including reviewing enclosure submittals and shop drawings, consulting on mockup construction and testing, resolving constructability challenges, and comparing as-built construction to the design intent

SGH also evaluated precast concrete panel designs to provide “proof of concept” for reinforcement and attachment, consulted on a wind tunnel study and developed concepts to address drift and facade panel movement, and peer reviewed the structural design for the tower and adjacent plaza waterproofing.
