Demolition Management—United Technology Center

Safely completed seven-year decommissioning and demolition of a major manufacturing site during transfer of the property from Brownfield to Greenfield Redevelopment.

Landmark successfully designed and managed the environmental decontamination and demolition of the 1MM square foot on 45 acre, former Hamilton Sundstrand Denver Metal Works facility. The facility included multiple buildings that began operations in the 1950s and was decommissioned in 2003 and 2004, then demolished in 2007 and 2008. Manufacturing processes in this facility included, machining, welding, electro-plating, painting, heat-treating, nondestructive testing, and waste treatment.

Landmark identified and managed contaminated soils and successfully developed the first Soil Characterization Management Plan (SCMP) in Colorado that was managed under dual regulatory jurisdictions. Our programs for the site were submitted during promulgation of new applicable regulations and yet our plans were accepted by the regulators with only minor comment.

Landmark provided “turn-key” services during the decommissioning phase and also preformed extensive industrial hygiene monitoring throughout the project for asbestos, metals, polychlorinated biphenyl (PCBs), and other chemicals during the demolition phase. Our staff also conducted hazardous waste evaluations and identified proper treatment and disposal methods for all wastes.

The property was developed in consortium with former owners, brownfield and Greenfield developers, municipalities, and state health regulators. This project was completed on time and within budget contingencies.
