TARGET DISTRIBUTION CENTER
Langan provided comprehensive site/civil design services for a 1.3 million square foot warehouse distribution center for this 130 acre site located along Interstate 81 near Chambersburg in central Pennsylvania. Langan designed and permitted all site improvements including detention basin design for over 150 acres of on-site and off-site development. Langan also designed and coordinated sanitary and water distribution systems for the regional center, and engineered a 3,000 linear foot roadway along the site’s frontage. Elements of our work included a fire water storage tank design, sanitary sewer planning through the Township and PADEP, and utility coordination. Challenging constraints to the design and construction included the presence of existing twin regional high pressure gas mains along the site’s border, and the concurrent construction of a new high pressure gas main. Detailed coordination in the roadway design, earthwork activities and blasting work were performed with multiple public and private agencies. Overall earthwork volumes in excess of one million cubic yards, and an estimated rock cut in excess of 700,000 cubic yards required a detailed geotechnical engineering study and preparation of site work specifications used by the contractor. Engineering inspection and oversight was provided during the geotechnical site investigation, and during earthwork and construction of the center.
