INTERSTATE CHEMICAL — PROCESS PLANT SITE DEVELOPMENT

Project Scope

E.S. Wagner Company completed the site development and foundation package for a 35-acre Sodium Methylate production facility in Oregon, Ohio, supporting a modular plant construction program on an accelerated schedule. The site work included approximately 65,000 cubic yards of earthwork, construction of two stormwater detention ponds, installation of erosion control measures, and placement of more than 50,000 tons of aggregate for roads, parking, and operational areas. ESW also coordinated installation of a 130,000-square-yard geomembrane containment liner and constructed more than 13,400 linear feet of underground utilities, including water, fire protection, sanitary sewer, and storm sewer systems. In response to owner-driven design changes, the team successfully converted major paving areas from asphalt to concrete and slip-formed approximately 12,000 square yards of 10-inch-thick pavement. The foundation scope included construction of more than 100 foundations supported by auger-cast piles and placement of over 8,800 cubic yards of concrete for process equipment and structural facilities. When unsuitable subgrade conditions were encountered, ESW rapidly implemented a soil stabilization solution, maintaining project momentum and protecting the aggressive construction schedule.
