Construction Engineering Services

A critical element of any construction project is to verify that the final product meets the design requirements and complies with drawings, specifications, permit conditions and designer’s intent. This is a necessary step for both documentation and certification purposes, and to give the owner and regulators confidence that the work has been completed correctly.

SCS provides the full-range of construction engineering and quality assurance services for construction of all elements of municipal and hazardous waste landfills, and solid waste facilities, remediation projects involving groundwater and soil extraction and treatment, LFG extraction and migration controls, and other environmental construction projects.

We offer a well-trained staff of field engineers and technicians that serve as resident engineers/owner’s representatives, soil and geosynthetics technicians, and LFG and groundwater well inspectors. Our experience encompasses construction projects of all sizes that include low hydraulic conductivity soil liner and cover systems, granular drainage media, the various types of geomembrane liners, geocomposite drainage products, geosynthetic clay liners, general earthwork, concrete, and mechanical and electrical systems.
