Former Forest Park Hospital – St. Louis Zoo Expansion

Location: St. Louis, Missouri
Client/Owner: Saint Louis Zoo
Services: Environmental

Geotechnology was selected to provide a wide range of environmental consulting services for the demolition of 9 buildings at the 13.5 acre former Forest Park Hospital site. The St. Louis Zoo acquired the site to create greenspace as they plan future expansion alternatives. Building footprints ranged from under one thousand to several hundred thousand square feet, and the site structures were in various states of disrepair as the site had been vacated. Geotechnology worked closely with the Zoo and their design and construction administration teams to develop a scopeĀ of work that would adequately address the following:

  • Preparation of a Phase I Environmental Site Assessment Report
  • Conducting limited soil and groundwater sampling and testing for screening purposes
  • Conducting asbestos and hazardous waste surveys
  • Conducting heavy metals-based paint (including lead) surveys
  • Preparing abatement cost estimates
  • Assisting with bid solicitation and review of contractor bids
  • Third party monitoring during the 7 months of abatement activities and removal of hazardous waste
  • Underground storage tank closure, including regulatory notification, soil and waste characterization sampling and the submission of a closure report for which the Missouri Department of Natural Resources issued a No Further Action letter
  • Periodic perimeter dust monitoring during demolition
