Conflicts resolution based construction temporary facilities layout planning in large-scale construction projects

Abstract

The construction temporary facilities layout planning (CTFLP) is important and complex in large-scale construction projects. During the CTFLP process, the general contractor has conflicts with many subcontractors regarding other pre-planning tasks, such as the transport routes planning (TRP). The resolution of the conflicts is crucial and this study attempts to determine the CTFLP considering conflicts resolution. Specifically, a novel methodology based on conflicts resolution between the CTFLP and the TRP is proposed, which can be adapted for future CTFLP based on resolving other types of conflicts. The two procedures-based methodology is composed of a bi-level model and a solution approach. The methodology is applied to a dam construction project in China to test the applicability, and the results show that it is able to obtain a satisfactory CTFLP and prevents some crucial conflicts, thus, promoting construction operations and making a significant contribution to the practice of construction projects.
