Site work for a water / sewer project in Philadelphia, Pennsylvania. Completed plans call for site work for a water / sewer project.

Project Overview Type: Firm Fixed-Price Construction Contract Location: Northeast corner of Castor & Delaware Avenues, Philadelphia, PA Setting: Industrial area, adjacent to government utility facilities Site History: Former Franklin Smelting & Refining Company (FSRC) and MDC Industries processed slag for roofing aggregate and abrasive grit. Operations ceased in 1999; interim remediation included grading slag pile and capping with 40-mil HDPE geocomposite liner. Environmental Impact: Fugitive dust and sediment affected nearby residential and light commercial areas. Final Record of Decision (ROD): August 2020 Goal: Eliminate future environmental risk and enable redevelopment to benefit local economy. Scope of Work Remediation of slag pile and surrounding impacted areas per ROD. Likely tasks: Removal or stabilization of slag material. Replacement or upgrade of interim cap. Site grading and drainage improvements. Environmental controls to prevent migration of contaminants. Compliance with EPA Superfund standards and health/safety regulations. Key Considerations Industrial setting but proximity to residential areas means strict dust and sediment control. Coordination with local authorities and adherence to community safety measures. Potential for redevelopment after remediation-design should support future land use.
