Project Highlights

  • 10-story and 6-story office buildings with 7-level ramp
  • Long spans
  • Cast-in-place concrete


Phase 1 involved the design of a 10-story, 415,000 square foot office building, framed with cast-in-place concrete and laterally braced with cast-in-place concrete shear walls. Long-span perimeter beams were post-tensioned to limit deflections, and custom pan layouts were used to increase bay sizes and reduce the number of columns. A pedestrian link leads from the office building to a 7-level precast concrete parking ramp, which holds 1440 vehicles. Total construction cost of Phase 1 was $93,000,000.

Phase 2 was a 300,000 square foot expansion, adding a 6-story office building, 2-story commons building with auditorium, and 2-story training center to the campus, as well as an extension of parking ramp. The office building is cast-in-place wide-module pan and joists, constructed with flying table forms, long-span post-tensioned girders, and an architectural precast fa├žade. The commons building uses composite steel framing with sloped raker beams, supported on yolked column supports in the auditorium. The exterior is clad with a combination of Pilkington structural glass and a tube steel curtainwall system supporting a granite veneer rainscreen. Phase 2 construction cost was $75,000,000.
