Engaged as a subcontractor by project manager EDMS, DEMEX undertook a technically challenging demolition of two industrial boiler stacks, 72 and 60 metres high. Due to excessive deterioration of the stack, particularly the internal brick wall, DEMEX identified the need for innovation, devising a solution that incorporated clever engineering design and robotic technology. Adopting an innovative methodology, the project was completed safely, ahead of schedule, and to the client’s satisfaction.
At tender, the client released its own demolition methodology based on completing saw cuts in sections, which would then be crane lifted from the stack. Excessive deterioration of the stack, particularly the internal brick wall, meant this methodology was identified as unsafe. Identifying the need for innovation, the team devised a solution incorporating clever engineering design and robotic technology.
DEMEX deployed the Brokk 200 demolition robot, a powerful two tonne machine that was remotely controlled by operators located on the ground and away from the work zone. The robot was positioned on a custom engineered and fabricated platform, which was crane lifted into position. The platform was then suspended marginally above the stack, preventing the structure from taking the full weight of the deck and robot, and eliminating the risk of excessive movement from wind.
