Construction Pre-Characterization

Coneco has provided Licensed Site Professional (LSP) services at an electrical substation project located in Salem, Massachusetts.  Due diligence research was conducted at the outset of the project in order to determine the likelihood that OHM would be encountered at the Site during the proposed construction activities.

Based on the due diligence research, a limited subsurface investigation was conducted in order to obtain representative laboratory analytical data in advance of the proposed construction project.  Based on the laboratory analytical data, a Release Abatement Measure was required during construction due to the presence of heavy metals in soil in excess of the Massachusetts Contingency Plan (MCP) Reportable Concentrations. 

Advanced knowledge of the contaminants present at the Site allowed for a timely and cost-effective solution that minimized construction delays and allowed for the protection of the on-Site worker's health and safety.  In addition, Coneco's early involvement in the project allowed for a real-time assessment of remaining contamination at the Site during RAM activities and a streamlined Site closure strategy.

Project Details

• Due diligence research to identify past Site use and/or known environmental conditions at a former rail yard.
• Pre-characterization in advance of proposed construction activities in order to assess the potential for oil and/or hazardous materials (OHM) in soil.
• Oversight, including all applicable MCP submittals, pertaining to the management of heavy metals-contaminated soil at the Site during construction activities.
