EFS was contracted by a client to perform concrete cover installation and related civil services at an active chemical plant in Ohio. The objective of this project was to construct a concrete cover system preventing rainwater infiltration and subsequent contaminant migration. The cover was constructed using materials designed to maximize durability and life, meet the requirements outlined in the Resource Conservation and Recovery Act (RCRA) 308(h) Administrative Order on Consent (AOC), and was conducted in accordance with project-specific Health and Safety, Quality Management, and Environmental Compliance Plans, including the NPDES Construction Storm Water Permit and Storm Water Pollution Prevention Plan.
EFS prepared site-specific plans for Health & Safety, Waste Management, Construction Quality Assurance, Traffic Control, and Environmental Protection. The scope of work included completion of pre-construction survey and site layout, preparation of site controls and establishment of erosion control measures, pouring of concrete test panels, demolition of site structures and above-ground features, demolition and loading of 45,000 square feet (sf) of existing asphalt, concrete, and gravel surfaces, removal and installation of overhead electrical service lines, installation of 260 linear feet (lf) of HDPE storm drain piping, HDPE manholes, and 160 lf of trench piping. The scope also included stripping, removal, and loading of 3,600 cubic yards (cy) of balance material and 3,400 cy of aggregate sub base, placement of 64,000 sf of geo textile and geo grid layers, installation of 56,000 sf of Liquid Boot membrane liner, cold weather placement of 1,600 cy of reinforced concrete, sealing of approximately 66,000 sf of new and existing concrete surfaces, and installation of force main piping, venting system, and isolation drain associated with revised construction plans.
All site activities were conducted in accordance with established work plans prepared by EFS and approved by the client, along with specifications and procedures developed by the client, the Environmental Protection Agency, and OSHA. During the construction phase, the client conducted a site-wide safety audit of EFS and the project site. Based on the findings of this audit, this project was nominated for an internal safety award within the commercial construction sector of the client’s company.
