Priestly Demolition (PDI) received two awards at the 2024 World Demolition Awards in Stockholm on November 7th. The company, in partnership with the Cameco Corporation and EllisDon, were awarded Contract of the Year over $1 million (U.S.), for the Cameco Building 27 Deconstruction project, and Contract of the Year under $1 million (U.S.) for the Glenbow Museum North East Stairwell Removal in Calgary.
Deconstructing a heavily contaminated seven-storey tower
The deconstruction and dismantling of Cameco’s UF6 Plant, commonly known as Building 27, was a successful project for both Cameco and Priestly Demolition. This seven-storey tower was heavily contaminated with radiological and chemical material, and had been sitting idle at the Port Hope Conversion Facility for decades.The two companies were dedicated to the safety, and to the environmental controls that were required to ensure the success of the project.
“Cameco was pleased to contract Priestly Demolition to remove the redundant UF6 building at the Port Hope Conversion Facility, however it was clear this was to be no normal demolition,” says George Trotter, program manager technical services for Cameco Corporation. “Unique solutions were required for this project along the way. It serves as an example to the demolition and nuclear industries that with careful planning, flexibility, creative solutions, patience, timely communication, and genuine care and dedication for the safety of all—the dismantling and safe disposal of a building contaminated with radioactive and chemical contamination such as the UF6 Building 27, is in fact possible.”
Glenbow Museum stairwell removal project
The North East stairwell removal at the Glenbow Museum was a unique and challenging complete demolition project that spanned just over 12 months. The former emergency stairwell was constructed of 1.8 million pounds of reinforced concrete that utilized a tower crane for its removal.
The location of the museum is in a heavily populated location, with many pedestrians and vehicle traffic surrounding the site. The crew had to be extremely careful not to drop a single piece of the 1,800,000 pounds of concrete that were removed.
