Critical success factors for modular integrated construction projects: a review

Modular integrated construction (MiC) is an innovative construction approach which transforms the fragmented linear site-based construction of buildings into an integrated production and assembly of value-added prefabricated prefinished modules. As MiC has gained attention in the construction industry, more in-depth knowledge of the critical success factors (CSFs) for implementing MiC projects is imperative. This research reviewed studies on the CSFs for implementing MiC projects during the period 1993-2019. Analysis showed that the US, UK, Malaysia, Australia, and Hong Kong are the largest contributors to the MiC CSFs studies. Further analysis generated 35 CSFs for implementing MiC projects. Of these, the six most cited CSFs shared between countries and MiC projects include good working collaboration and effective communication among project participants; effective supply chain management; accurate design and early design freeze; involvement of key project participants throughout the project; suitable procurement strategy and contracting; and standardization & benchmarking of best practices. These shared CSFs can be used to develop decision support systems, enabling the prediction of project success. The developed checklists and conceptual model of the CSFs could help to guide and improve the successful implementation of MiC projects and may form a useful basis for future empirical studies.
