Current approaches for solving tolerance-related issues in modular construction consist of trial and error tactics, which are inefficient, time-consuming and not risk-averse. Although tolerance management is not new to the construction industry, tolerance issues are usually more problematic for module interfacing and transportation in modular construction. This paper introduces a framework for the development of tolerance strategies for mitigating risks in modular construction systems. Risks affecting specific types of modular projects were investigated and developed into a comprehensive tolerance strategy, which was then validated through a case study of an industrial pipe chassis. The proposed methodology may be more effective than the conventional approach for tolerance definition (i.e., trial and error methods), and has the potential to eliminate rework, decrease project costs and reduce delays experienced in modularization by providing a range of pareto-optimal design solutions for “strict” to “loose” tolerance control with respect to the hypothesized costs and risks.
