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