Brownfield Redevelopment

Under the New York City E-Designation Program, Liberty prepared a Remedial Investigation and Oversight of a former commercial property that was redeveloped as an ultra-modern apartment building with high-end amenities located in Jamaica Queens.

Initial tasks included performing a Phase I ESA, attending a scoping meeting with OER, preparation of a Phase II Work Plan, performing soil, soil vapor and groundwater investigations, preparing a Remedial Investigation Report, and preparing Remedial Action Work Plans for hazardous materials, noise and air.

The scope included design of a sub-slab vapor mitigation system to mitigate the potential for vapor intrusion. During construction Liberty personnel performed ambient air quality monitoring, management of contaminated soil excavation, and inspections of the vapor barrier installation.
