Recipes for Cost and Schedule Successes in Industrial Modular Projects: Qualitative Comparative Analysis

Modularization is a well-established method that can improve the efficiency and effectiveness of the construction industry. However, the industry continues to struggle with its implementation, and not all executed modular projects have resulted in successful project performance. This study investigates the combinatorial effects of modularization critical success factors (CSF) on the cost and schedule performances of industrial modular projects and derives a conceptual model of cost and schedule successes using information from actual cases by applying crisp-set qualitative comparative analysis. The findings confirm that CSFs interactively and collectively affect modular industrial project performance. The most commonly involved CSFs for cost and schedule successes are timely design freeze, owner-furnished/long-lead equipment specification, vendor involvement, and management of execution risks. This work contributes to researchers and practitioners in the industrial sector to improve understanding of the recipes (i.e., CSFs or combinations thereof) for successful modular project planning and execution, which will lead to improved modular project performance in the construction industry.
