The plot around where the building to be demolished is situated and barricaded. The debris is removed from the site after the building is demolished. The foundation of the building is also removed below the ground level.
The demolition contractors prepare a comprehensive plan before proceeding with the task of demolition. The method of demolition is determined on the type of frame used in the construction of the building such as steel frame or concrete frame. The structure is also tested for the presence of asbestos and other materials. Power, sewer and all other utility lines are disconnected from the building before demolition is carried out. The materials that can be recycled or reclaimed after demolition are identified along with their approximate volumes.
Demolition contractors also work with commercial property owners, project developers and general contractors. Apart from office buildings and retail stores, the demolition contractors are also available for demolishing decommissioned factories and plants. In case of plants and factories, the demolition experts initially first determine on whether or not any decommissioned equipment can be reused or recycled.

Concrete crushers are also deployed during demolitions to crush materials such as concrete, bricks, rocks, asphalt, etc to pieces of smaller dimension. The crushed materials are easy to transport on trailers. The materials can also be used for another project which saves money. Dust suppressing equipment to check flying dust is also being used by demolition contractors.
The type of equipment required for demolition is dependent on a plethora of factors such as the height of the building, type of concrete, time limit of demolition, space around the building, size and quantity of reinforcement used in the building and the age.
Explosive materials can also be used to demolish buildings. The explosion causes the building to collapse in seconds without causing damage to the nearby structures.
