Dismantling buildings

Dismantling involves the careful deconstruction of building components for repair, re-use, re-purposing or recycling. Dismantling differs from deconstruction in that it can be undertaken as a means of conservation, maintenance and repair works, whereas deconstruction involves taking a building down, albeit in a careful way that aims to minimise waste and maximise re-use. Dismantling also differs from demolition in that it does not generally involve the clearance of an entire structure.

Dismantling can be required on projects where it is necessary to remove intricate components, where there is a safety risk (for example if a structure contains asbestos or other hazardous materials), where it is necessary to move a component from one place to another, or where the structure and/or surrounding environment is particularly sensitive.

The cost and time required for dismantling depends on factors such as; complexity, volume, site conditions, building type, time availability, materials and techniques used, available records and so on.

According to the Construction (Design and Management) Regulations (CDM Regulations), all dismantling work should be carefully planned and carried out by competent professionals to avoid unplanned structural collapse.
