Before any demolition activities, there are many steps that need to take place, including but not limited to: performing asbestos abatement, obtaining necessary permits, submitting necessary notifications, disconnecting utilities, rodent baiting and development of site specific safety work plans.
The typical razing of a building is accomplished as follows: Hydraulic excavators may be used to topple one or two story buildings as seen, or by an undermining process. The strategy is to undermine the building while controlling the manner and direction in which it falls. The demolition project manager/supervisor will determine where undermining is necessary so that a building is pulled in the desired manner and direction. The walls are typically undermined at a building’s base, but this is not always the case if the building design dictates otherwise. Safety and cleanup considerations are also taken into account when determining if or how the building is undermined; and ultimately demolished.
