General Contractor: Clark / Balfour Beatty, JV

Precast Erector: E.E. Marr Erectors

This mega-project, which included over 1500 panels & 260,000 square feet of blast-resistant architectural precast, was made up of two large crescent shaped buildings connected by a huge clearstory atrium. The precast clad the majority of the elevations on the outside of the crescent.

The majority of the panels were extremely large faceted window units with trapezoidal shaped window openings and angled V-Shaped jamb sections. The molding surfaces for these panels had to be exact as the straight & trapezoidal intersections all had to align. This was accomplished by building a master plaster model. Off this master model, four concrete molds were made all with the exact same proportion. Off these four molds over 600 panels were fabricated with perfect alignment. This process is well detailed under “Our Process” section.

The end result was a well-proportioned building with unique lines and profiles, which catches your attention, not for its size, but for its beauty and sharpness.
