Sigma assists community center redevelopment project



The Sojourner Family Peace Center had acquired a three-acre parcel (entire city block) occupied by a 60,000-square-foot, two to three-story multi-winged building built in 1970 for future redevelopment as a family advocacy services/housing complex and administrative offices. The facility once served as a 125-bed skilled nursing facility and was vacated for over five years and in deteriorating condition prior to razing.

The Sigma Group served as the environmental and civil consulting engineer for the razing of the buildings and site preparation/grading in advance of redevelopment from the initial planning through project closeout.

  • Performed due diligence of property as part of real estate transfer including Phase I Environmental Site Assessment.

  • Conducted hazardous materials pre-demolition inspection for lead-based paints, oil, refrigerants and PCBs including LBP coated concrete analysis.
