The Pinellas Board of County Commissioners has hired SCS Engineers to manage its side slope closure project at the Bridgeway Acres Landfill. SCS will also provide construction quality assurance, construction contract administration services, and geosynthetic materials conformance and field test services.
When portions of a waste site are closed special skills are provided by SCS’s environmental engineers to control leachate formation and landfill gas. The stability of the cover system is ruled by the shearing resistance that develops at the interfaces of various components of the cover systems. The slope angle, slope length, surface roughness of the geomembrane and tensile strength of the veneer reinforcement influence the stability of slopes. The impact of seepage forces also affects long-term stability and safety. The County has chosen to use a geomembrane cover, which with the conformance and in-place testing along with proper installation help to secure the longevity and stability of the slopes in the closed portions of the landfill.
