Various Sites in the United States
Sevenson’s MSA has included over 35 individual task orders requiring environmental remediation and long-term operation and maintenance services at priority Olin sites across 11 states. Sevenson has excavated and handled a variety of hazardous contaminants at these sites, including asbestos, mercury, sludge, caustic liquids, PCBs, PAHs, lead, arsenic, VOCs, SVOCs, heavy metals, and pesticides.
Sevenson has successfully implemented the use of a design-build “partnering” approach with the engineer and owner on various projects under this MSA which has resulted in a strong working relationship. By participating in constructability review during the remedial design phase of the project planning process, Sevenson and the engineer are able to develop clear, well-prepared project documents, reducing potential changes and delays in the field after construction work begins. Sevenson executes a wide range of environmental remediation services, including; excavation and handling of contaminated soil, debris, and mixed media; operation and maintenance of WWTPs; structural demolition; earthwork; coordination of transportation and disposal of materials; construction and installation of caps; site restoration; and site monitoring.
