Tysons Corner Center Structural Engineering

Location: Virginia; United States; North America

Tysons Corner Center provides the first direct link to visitors and commuters from across the Washington DC Metro Area to northern Virginia. Cardno engineers designed a 20-story, 526,500-sf office building, a 30-story, 500,000-sf residential tower, and a seven-level, 906,200-sf parking garage podium. The office and residential towers sit above the parking garage podium with two levels above-grade, one level at grade, and four levels below-grade. Both towers are linked by a pedestrian plaza with direct access to the new Metrorail station and Tysons Corner Center retail complex. 

Tysons Tower office building is rated LEED Gold offering green roof, floor-to-ceiling windows, and solar shades on the southern exposure to capitalize on natural sunlight for energy management. The residential tower soars 350 feet above street level and 40 feet above the office tower and is pursuing LEED silver certification.

Structural challenges included the design of the parking podium, which was under construction for nine months before the completion of the design of the residential tower that it supports. Cardno coordinated dimensional accuracy, slip connections, and expansion joints to accommodate lateral movement and heavy loading at seven unique support points. Also of special note is the glass cable wall system along the main facade of the office tower, one of the largest of its type in the country, and the first in the DC Metro area.
