Bierrum International specialize in the design, construction, repair, maintenance and demolition of tall reinforced concrete structures particularly chimneys, cooling towers and silos and they work on a worldwide basis.

Through their knowledge of the chimney industry, it became clear that there was a requirement for a methodology to be developed to demolish chimneys in difficult environments where there was live plant in close proximity to the structure. Bierrum developed the “Spider” demolition tool which has been used successfully on several 180m high chimneys in the UK and is currently being used on the “B” station stack at Rugeley.

Innovative Demolition of a 180m chimney with the Bierrum “Spider”

In 2006, Rugeley Power commenced the design and construction of a Flue Gas Desulphurisation installation at their Rugeley Power Station. The project involved the construction of a new 180m high chimney. The existing chimney needed to be demolished but it was situated very close to existing and new plant and the client specified that no material was allowed to fall outside the chimney.

Rugeley Power contracted with Bierrum International Ltd to use their “Spider” demolition system to ensure the safe and speedy removal of the structure without the need for expensive protection works to the surrounding equipment.
