ERG performed environmental due diligence services for 57 vacant and dilapidated commercial properties targeted for demolition throughout the City of Detroit. The Detroit Building Authority (DBA) contracted ERG to perform both a Phase I Environmental Site Assessment (ESA) and a Hazardous/Regulated Materials Survey at each of the properties. The Phase I ESAs were conducted in compliance with ASTM E 1527–13, and the Hazardous/Regulated Materials Survey were performed in compliance with the City of Detroit Scope of Services, and included sampling and assessment for asbestos containing materials (ACMs), lead-based paint (LBP), polychlorinated biphenyls (PCBs), and other potentially hazardous materials. 

The DBA required that all of the assessments be completed within six weeks of contract award. In order to accommodate the short timeframe, ERG devoted several personnel to the project, and utilized work and task efficiencies to successfully complete the assessments within the allotted time.

The properties were formerly occupied by various commercial businesses, including gas stations, dry cleaners, grocery stores, dry goods stores, apartments and other retail and/or service operations. Many of the parcels were identified with recognized environmental conditions (RECs) requiring further investigation. It is anticipated that ERG will conduct Phase II ESAs on the properties with RECs in February and March of 2016.
