Multi-criteria decision analysis for tower crane layout planning in high-rise modular integrated construction
Abstract Tower crane layout planning (TCLP) is critical to high-rise modular integrated construction (MiC) that involves multiple heavy-duty lifts. However, previous studies have rarely addressed TCLP in modular construction. This study thus develops a new decision-making framework for selecting an optimal tower crane layout for high-rise MiC. First, the feasibility and performance criteria considering MiC-specific features are established based on a critical literature review and expert interviews. Second, a two-step framework of TCLP is proposed with fuzzy-integrated techniques for feasibility assessment and performance analysis. Third, the framework is validated using a real-life MiC project. Results indicate that the framework is effective in balancing the safety and economic performance of a crane layout, and the performance is considerably sensitive to modularized floor plan and weightings of criteria. By proposing the new framework of TCLP with multi-criteria decision-making techniques, the paper should facilitate safe and efficient module installation in high-rise MiC.
Highlights A new TCLP framework was developed with feasibility assessment and performance analysis A hierarchy of criteria was established considering MiC-specific features, e.g., rotation of modules An integrated fuzzy-AHP-TOPSIS approach was first attempted in crane-lift planning Substantial trade-offs were found to exist in safety performance and economic efficiency Crane layout design is sensitive to modularized floor plan and weightings of criteria
