Site Investigation, Demolition, Remediation and Clearance of Former Modern Electroplating Facility
Weston & Sampson was retained by the Boston Redevelopment Authority (BRA) to provide professional environmental and engineering services in support of the redevelopment of the former Modern Electroplating facility in Roxbury, Massachusetts. The BRA was tasked by the Mayor to prepare the facility for relocation of Area B-2 police station.
As part of the Dudley Vision Plan, the facility was used for solvent degreasing, spray painting, metals polishing and several types of plating including chromium, cadmium, copper, nickel and zinc. The facility ceased operation in 1995, and the EPA removed and disposed of numerous drums, paint cans, laboratory chemicals and wastes from vats. Weston & Sampson performed the following:
- Site investigation and development of a remediation plan
- Building demolition, remediation, and site clearance design
- Chapter 149 public bidding and construction oversight
Site Investigation and Development of a Remediation Plan
Weston & Sampson advanced soil borings and installed wells throughout the property and sampled and analyzed indoor air, soil, groundwater, trench water and sludge, concrete slab, vats, debris, and building materials. The results indicated elevated concentrations of metals in soil, metals and chlorinated solvents in overburden and bedrock, low levels of chlorinated solvents in indoor air, and asbestos containing materials (ACM) and lead-based paint (LBP) in buildings. In addition, metals and cyanide were detected in concrete, vats and debris.
Building Demolition and Site Clearance Design
Weston & Sampson performed a utility survey and prepared plans and specifications for building demolition and site clearance. The demolition and site clearance work included abatement of ACM and LBP, removal and disposal of debris, removal/reuse of vats impacted by metals and cyanide, removal/disposal of contaminated concrete as hazardous waste. In addition, building materials including concrete were reused on site under a beneficial use determination from the Department of Environmental Protection (DEP).
Remedial Design, Construction Oversight and MCP Compliance
Weston & Sampson performed an evaluation of remedial alternatives, developed a remediation strategy, prepared plans and specifications and provided construction administration and oversight services for relocation of the police station. The project was bid under MGL Chapter 149 bidding laws. The site has been redeveloped and is now the location of the new LEED®-certified Area B-2 Police Station.
