Scope of Work
The project posed several logistical challenges due to record snowfalls during the winter of 2014-2015, impacting both transportation and site activities. Extensive snow removal was required to provide safe access to work areas and enable demolition work.
Delsan-A.I.M. prepared each structure for demolition by identifying and disposing of hazardous materials, and confirming that all utilities had been safely disconnected. The project also included the cleaning and demolition of nine above-ground storage tanks used for bunker C, diesel, gasoline, and waste oils.

Execution
Decommissioning
Once decommissioning was complete, Delsan-A.I.M. proceeded with demolition using mechanical methods, including high-reach demolition excavators and conventional excavators.

Demolition of Higher Structures
For taller structures beyond the reach of conventional equipment, Delsan-A.I.M. employed control-drop methods, including explosives, to safely bring down structures in a controlled manner.

Explosive Demolition of Headframe Building
Delsan-A.I.M. used explosives to demolish a headframe building, located directly above the No. 3 Shaft and housing hoisting equipment. The building, a reinforced concrete structure, had a footprint of 68 ft. by 46 ft. and a height of 257 ft. The demolition required maintaining the reinforced concrete floor capping the mine shaft during the operation, necessitating detailed planning and engineered procedures outlined in a comprehensive Blast Plan.

Project Success
Delsan-A.I.M. successfully completed the decommissioning and demolition of the Brunswick Mine site, overcoming significant logistical challenges and utilizing a combination of mechanical and explosive techniques to ensure the safe and efficient removal of assets and structures.
