Demolition Management—Former St. Luke’s Hospital


Aggressive and proactive contractor management minimized environmental change orders to less than 3 percent of the gross project value.


This asbestos abatement, structural demolition and hydrocarbon in soils remediation project included the largest ever asbestos removal action in the State of Colorado. Landmark’s scope of work included abatement and demolition of 13 structures totaling over 2.5 million square feet and the redevelopment of five city blocks in downtown Denver. Three of the project structures were higher than 10 stories, and buildings were abated and demolished in a highly active core urban area.

Project Highlights

  • Environmental cleanup was performed simultaneously with structural demolition. The work was completed on schedule in only nine months.
  • Excavation of 60,000 cubic yards of hydrocarbon contaminated soils to a depth of 60 feet was performed at locations adjacent to standing structures. This required development and implementation of comprehensive excavation, shoring and haul route procedures.
  • Abatement of over 1 million square feet of asbestos-containing material (ACM) included the complete interior demolition of a 13-story structure.
  • Landmark’s management of safety and industrial hygiene resulted in no safety violations, citations or lost-time worker injuries.
  • Cost savings of over $3 million were achieved through asbestos abatement variance protocols leveraged by Landmark. Cost uncertainties were controlled through detailed building inventories and aggressive building asset recovery and recycling programs.
  • Aggressive and proactive contractor management minimized environmental change orders to less than 3 percent of the gross project value.
