Demolition Design and Management—Former Mercy Medical Center and St. Anthony’s Hospital


Project uncertainty reduced with a strategic and targeted sampling approach that carefully evaluated construction renovation history.


Landmark successfully completed asbestos, regulated building material (RBM) and hazardous material assessments and abatement design documents prior to the cleanup and demolition of the former Mercy Medical Center and St. Anthony’s Hospital. These projects combined included environmental abatement and demolition of seven structures totaling more than 1.5 million square feet and included redevelopment of six city blocks.

Project Highlights

  • Landmark’s thorough knowledge and application of regulatory requirements was a key contributing factor to the successful completion of these projects. By working closely with regulators and other stakeholders, Landmark identified and designed important value-engineering processes that controlled costs and promoted effective completion of the projects.
  • Prior to performing sampling and analysis during the hazardous materials surveys, Landmark exhaustively reviewed historical reports for reliability so that redundant sampling efforts were not required.
  • Landmark’s extensive experience in projects similar in scope and size resulted in a targeted sampling approach that resolved key scope uncertainties and promoted constructability.
  • Prior to conducting surveys, Landmark completed comprehensive Phase I Environmental Assessment in accordance with ASTM and EPA-AAI requirements that included evaluation of the potential for discovery of asbestos in soils.
  • A key scope uncertainty related to asbestos spray applied fireproofing was resolved with a strategic and targeted sampling approach that carefully evaluated construction renovation history. Landmark successfully confirmed and obtained regulatory approval indicating that the majority of areas previously reported to be asbestos contaminated were, in fact, not.
  • Abatement and subsequent demolition confirmed that Landmark had accurately identified and designed key environmental abatement procedures. No significant unforeseen environmental conditions or changes to scope of hazardous material removal occurred.
