Quantitative evaluation and ranking of the critical success factors for modular integrated construction projects

Modular integrated construction (MiC) is becoming a preferred construction approach for many types of building projects. However, several factors and conditions must converge to determine the success of MiC projects. This research identified and evaluated 25 critical success factors (CSFs) for implementing MiC projects. The dataset was generated through a structured questionnaire survey and analyzed using robust statistical techniques. Based on the mean scores, the top five CSFs for MiC projects include fabricator experience and capabilities in modules design and production; robust drawing specifications and early design freeze; good working collaboration, communication and information sharing among project participants; standardization and mass production; and effective coordination of the supply chain segments. An exploratory factor analysis generated four principal success factors (PSFs), comprising adequate technical capability and infrastructure; effective stakeholder and supply chain management; early commitment; and standardization and benchmarking. A fuzzy evaluation revealed that all the four PSFs are paramount to the success of MiC projects. As a contribution, the research has identified and prioritized the CSFs which may help MiC project managers and stakeholders in the appropriate allocation of limited resources. These shared CSFs may constitute forecasting and diagnostic tools for progressively measuring success along the MiC project lifecycle phases.
