For the Trex Warehouse in Winchester, VA, The Shockey Precast Group manufactured and erected 206 jumbo insulated precast wall panels, approximately 15′ x 38′ in size. The panels were used as load-bearing members for the roof structure, which eliminated the need for exterior columns and beams. In addition to offering cost savings for the owner, the use of precast offered an overall construction schedule that was shorter in duration than the schedule for steel erection.
