Many of these projects are highly complex, often located next to railway lines or rivers, and can involve significant contamination from asbestos, radioactive materials, and hydrocarbons. Cognition is also experienced in completing standard demolition projects, to the satisfaction of our valued clients.

In addition to demolition, Cognition also provides comprehensive decommissioning services that complement our demolition capabilities. Cognition further specialises in storage tank removal, a process that frequently involves degassing, dewatering, and sludge removal. Our team is experienced with above-ground and underground tanks, including fuel, chemical, and gas-holding structures.

As a testament to our expertise, Cognition was awarded ‘Demolition and Enabling Specialist of the Year’ at the CN Specialists Awards 2025.
