The Project : Installation of three below grade oil water separators capable of processing 3,000 gallons of contaminates for the USCG required Edgewater to first eliminate over 15 cubic yards of Extra Contaminated Soil. Once eradicated, Edgewater installed 3 below-grade oil/water separation systems entailing effluent pumps; 4, 6, 8 and 18-inch gravity piping; precast concrete manholes; two small sump pumps with 2-inch and smaller force mains; 2 and 4-inch force mains. This project required horizontal directional drilling of approximately 280 feet of 4-inch force main; concrete cutting and replacement; excavation; electrical work; demolition of the existing submersible pump station and wet well; and demolition of the existing oil water separator.
The Challenge: This project had a subcontractor that could not perform up to the safety and quality standards held by Edgewater.
Value Added: Edgewater contracted and deployed a new subcontractor to the satisfaction of the USCG with minimal impacts to the schedule and budget.
