AEC was retained by the client to perform closure of a clarifier solids landfill in St. Helens, OR. The overall scope of work was to construct a six-acre closure cover over the existing disposal area of a clarifier solids landfill. Along with initial clearing, grubbing, and heavy grading activities, we installed 270,000 square feet of geomembrane liner, 62,000 square feet of geocomposite drainage layer, 10,000 tons of imported sand layer, 16,000 cubic yards soil cover layer, 4,290 lineal feet of gas collection trench with pipe, and other miscellaneous work. The project required us to procure, manage, and perform strict quality control on large quantities of import materials such as rip rap, sand, geotextile, and pipe.
