After the construction of Gateway Business Park Building #5, an additional building was built to the south, expanding the industrial park. Located in Plainfield, IN, project leaders sought an efficient building envelope solution to keep pace with the community’s growth. Prestressed Insulated Sandwich Walls were selected for their significant time and cost savings. County Prestress manufactured and delivered more than 140,000 SF of insulated sandwich walls for the building. The prestressed panels offered a reliable, timely solution.
