This two-phase parking structure project consisted of site grading; the export of 20,000 cubic yards of soil; the installation of a 12-foot-high-by-1,000-foot long retaining wall along the highway; and utility work over 5.2 acres. The second phase involved the construction of an 180,000-square-foot, 462-stall parking garage with 8,400 square feet of office space. The garage is a cast-in-place, posttensioned, four-level structure with a photovoltaic panel system installed on the roof.
Halfway through the project, the client elected to pursue LEED Silver certification for the new parking garage. The City did not have experience with sustainable construction efforts, and the contract documents did not lend themselves to an easy transition toward certification. In response, PCL — at no cost to the client — coordinated and organized the appropriate paperwork and documentation for the contractor LEED submittals. The team also prepared material costs data sheets, compiled waste management and diversion reports, prepared and implemented an indoor air quality plan, and commissioned the facility to achieve the desired certification.
