Phase I of the campus includes two 10-story office buildings, totaling 555,000 sf, connected by a double height lobby, upper level sky bridge, and a roof canopy. On either side of the lobby are double monumental stairs, which connect all floors. The structural system for the building consists of concrete moment frames and pan joist with post-tensioned girders.
Cardno incorporated unique structural elements for the project. The double height lobby creates a dramatic entry to the building and was designed structurally using steel braced frames with open web joists and wide flange girders. A sky bridge at the 9th floor offers a link for travel between the towers. Its floor is suspended from the structural roofing of the bridge. The building’s roof canopy provides an architectural detail as well as acts as the support for the window washing units. Both the sky bridge and canopy were designed to conceal the fact that they cross an expansion joint between the two buildings. The second floor houses a 20,000-sf data center. Basement and tunnels are located below-grade.
