This 125,000-sq-ft high school sits on a 20-acre site and includes a three-story academic wing with 53 classrooms and nine science labs, including a hospital simulation room with three beds, an outdoor plaza, a teaching kitchen, and paved concrete parking for 316 vehicles. The structure was composed of 539 precast concrete units—including walls, beams, columns, and double-tees—in just over 11 weeks and included 4,500 cu yd of concrete and 163 tons of steel. Although precast concrete offered several benefits, special considerations had to be given to the support of such a heavy structure on top of unforgiving, mucky soil. The team used roughly 1,200 70-ft-long composite timber piles to support the building. SES provided soil and concrete testing services throughout the duration of this phase of construction. We also performed vibration and pile monitoring, steel and welding inspections, and coating inspections for the project.
