Critical Review of Tolerance Management in Construction

The current practice of Tolerance Management (TM) is still very ad hoc and reactive, despite increasing calls for waste reduction and an improved quality of buildings particularly within industrialised construction. This paper aims to identify the root causes of tolerance problems, the reasons why current methods have not been as successful as expected and why the industry still struggles with this issue. Having reviewed and interpreted the existing literature, it is apparent that tolerance problems fall into two categories defined by intrinsic and extrinsic factors. Furthermore, the drawbacks of the existing methods for TM were analysed, and the findings show that none of the existing methods have been considered in a continuous and holistic process and they remain scattered.
