Scope of Work
The project encompasses the removal of significant structures, including:

• The original powerhouse, divided into four (4) sections, each with a footprint of 20,000 sq. ft. and a height of 220 ft.
• Two (2) selective catalytic reduction converters, each standing 175 ft. high.
• Two (2) absorber buildings at 211 ft. high.
• Three (3) reinforced concrete stacks, each measuring 550 ft. high.
• Additional secondary structures, such as two (2) pumphouses and an administration building.

Decommissioning and Preparatory Work
The decommissioning phase included the removal and disposal of designated substances and hazardous materials over a nine-month period. This process involved extensive asbestos abatement and thorough dust cleaning within the remaining boiler bays.

To facilitate access and waste material removal during abatement, Delsan-A.I.M. installed construction elevators adjacent to each boiler bay.

As part of preparatory measures, Delsan-A.I.M. permanently isolated the condenser circulating water (CCW) pipes and installed custom-designed protective covers over the forebay and outfall channels that connect the St. Clair River to the station. These measures prevented dust and debris from entering the water channels and ensured the safe isolation of the pumphouse intakes before demolition.

Demolition Operations
Following months of detailed planning and site preparation, the demolition operations commenced with precision. Explosives were used to simultaneously demolish the boiler bays, selective catalytic reduction converters, and three (3) stacks in accordance with a comprehensive engineered blast plan. The plan prioritized the safety of site personnel, the public, and the surrounding environment.

Environmental and Safety Measures
Delsan-A.I.M. implemented numerous environmental and safety protocols, including:

• Scheduling explosive demolition activities to minimize impacts on aquatic life, fish spawning, bird nesting, and wildlife breeding seasons.
• Establishing a fully cordoned-off exclusion zone during blasting operations to protect the public and site personnel from debris and dust.
• Monitoring meteorological conditions to ensure dust traveled away from public areas and neighboring properties, including the St. Clair River.
• Installing protective barriers, such as sea containers and geotextile walls, to safeguard critical on-site infrastructures, including an active switchyard.

Project Completion
This highly complex project reflects Delsan-A.I.M.'s commitment to safety, environmental stewardship, and meticulous planning. Through innovative techniques and rigorous adherence to engineered guidelines, the Lambton Generating Station site is being transformed safely and responsibly, leaving a positive legacy for the community and the environment.
