Estimating demolition costs for single residential buildings

With the increasing stock of aging structures, building<br />demolition is becoming achallenging research field from<br />the perspective of management. As the converse of<br />construction, management of demolition puts forward some<br />new management themes or adds some new contents<br />even though the same issues are faced in construction<br />management. This research aims to develop a quantitative<br />approach to estimate the costs of a demolition project. A<br />cost analysis method is presented to systematically break<br />down the cost components involved in the demolition of<br />a structure. Due to the lack of robust research in theory<br />and systematic summary in practice to date, the economic<br />performances of demolition will be studied through acase<br />study, and the majority of parameters are derived from<br />actual experiences in practice. The proposed demolition cost<br />estimation method is applied to the actual form of building<br />elimination (Scenario 1), and further comparison is carried<br />out with two other elimination methods, which are the newly<br />developed deconstruction (Scenario 2) and mechanical<br />demolition (Scenario 3). Deconstruction is found to be the<br />most profitable in this particular instance, and is closely<br />followed by the actual form.
