Giant Mine Roaster Complex Decontamination and Deconstruction


Next to Ingraham Trail outside Yellowknife, Northwest Territories


Public Works and Government Services Canada and Aboriginal Affairs and Northern Development needed to deconstruct the Giant Mine Roaster Complex buildings which were at risk of collapsing, potentially releasing asbestos, arsenic trioxide, cyanide and other hazardous materials into the environment. AECOM and sub-consultant Golder completed the assessment, project design and contractor supervision. Multi-faceted work control standards were developed in order to: minimize exposure to asbestos, arsenic, cyanide, and arsine gas by on-site workers; protect the public and the environment; and confirm when decontamination was complete.
