Abstract
Building information modeling (BIM) and modular construction are important technologies for construction industry sustainability. This study proposes a relational matrix of key activities and BIM tasks of modular construction projects to analyze practical BIM tasks in Korea. To achieve this objective, 11 key activities and eight BIM tasks are identified through a comprehensive literature review and expert interviews. Then, the relational matrix of key activities and BIM tasks is proposed, and the BIM tasks in the matrix are analyzed in terms of necessity and efficiency using 5-point Likert scales. Finally, the matrix with the BIM utilization index is suggested. As a result, the average BIM utilization index is 0.80 in the off-site phase, and the index results show that 3D shop drawings have the highest index. In the on-site phase, the average BIM UI is 0.73 and the integration of a 4D model with quantity take-off is the most efficient at 0.85. Additionally, from the decision-maker’s perspective, the priority through the index presented helps in making decisions and in practical BIM execution planning. The proposed matrix is a practical reference for decision-makers considering the application of BIM in modular projects, and it contributes to a sustainable construction industry.
Highlights
Modular construction and building information modeling (BIM) are recognized as important technologies to overcome the current crisis in the construction industry [1,2]
The factors and the corresponding index of the relational matrix in this study may depend on the characteristics of modular projects, decisions of the BIM manager, and job description of the project
BIM and modular methods are recognized as important technologies for sustainability [2,3]
Summary
Modular construction and building information modeling (BIM) are recognized as important technologies to overcome the current crisis in the construction industry [1,2]. BIM and modular technologies are highly interrelated and can be applied together to maximize profits for the construction industry [2,3]. It is recommended that BIM and a modular method be used jointly to improve the performance of the construction industry [4]. Because the construction industry generates more waste and consumes more energy than other industries, there is a need for measures to improve these aspects [1,2,3,4]. To this end, it is necessary to eliminate inefficiency in the construction process. Off-site construction, such as the modular method, and the use of BIM are suggested as available options [2,3,4,5,6,7]
