Excavation and earthwork are core services at Sevenson. They are services that go back to our earliest involvement in site remediation. Sevenson’s predecessor, the Albert Elia Building Co., Inc., participated in western New York’s infrastructure expansion in the 1960’s. AEBC built roads and bridges throughout the region as well as installed miles of large diameter pipe associated with water and wastewater systems. Elia’s focus on heavy civil construction made the transition into environmental remediation smooth. This heavy civil skill set was passed down through the years to company personnel. It fueled Sevenson’s growth in the environmental business as the demand for additional civil construction techniques (steel sheeting systems, landfill construction and closure, solidification and stabilization) grew as projects became more complex in scope.

As Sevenson transitioned from a general construction contractor building highways, bridges, sewers and other civil works to a dedicated full-service environmental remediation contractor, Sevenson drew heavily on that construction experience while developing the know-how and experience to tackle larger and more complex environmental remediation projects. Projects often call for the same or similar know-how and skills that Sevenson possessed as a general contractor, particularly in excavation and earthwork construction.

  • Completed hundreds of environmental projects requiring removal actions, landfill construction and closures, and material handling and processing
  • In 2012, a $90 million expansion project for the Delaware Solid Waste Authority at its Cherry Island facility in Wilmington, Delaware, earned the project’s design and construction teams a nomination for the American Society of Civil Engineers OPAL Award for outstanding civil engineering achievement

We have successfully developed and implemented site specific health and safety plans since 1979. With a full time staff of 30 full-time Health and Safety Officers that include CHST’s and OHST’s, our Site Safety and Health Officers average 14 years of service.
