Estimating Demolition Costs for Single Residential Buildings

Abstract

With the increasing stock of aging structures, buildingdemolition is becoming a challenging research field fromthe perspective of management. As the converse ofconstruction, management of demolition puts forward somenew management themes or adds some new contentseven though the same issues are faced in constructionmanagement. This research aims to develop a quantitativeapproach to estimate the costs of a demolition project. Acost analysis method is presented to systematically breakdown the cost components involved in the demolition ofa structure. Due to the lack of robust research in theoryand systematic summary in practice to date, the economicperformances of demolition will be studied through a casestudy, and the majority of parameters are derived fromactual experiences in practice. The proposed demolition costestimation method is applied to the actual form of buildingelimination (ScenariO 1), and further comparison is carriedout with two other elimination methods, which are the newlydeveloped deconstruction (Scenario 2) and mechanicaldemolition (Scenario 3). Deconstruction is found to be themost profitable in this particular instance, and is closelyfollowed by the actual form.
