Abstract

Background:
Site layout plan is one of the important decisions to be made in the planning phase of each construction project as it can significantly impact on-site transportation, construction logistics and safety. This decision could be complicated due to the uncertainties inherent in construction projects and the complex relationships between the influencing factors and decision variables.
Methods:
To improve site layout planning, this study aims to develop a simulation-based decision support tool (DST) that enables planners to consider: 1) construction uncertainties, 2) construction resources (i.e., material, equipment and workers), 3) site layout constraints, and 4) mutual impacts between site layout and construction plan variables, for site layout planning of construction projects. Results:
The developed DST visualizes the site layout plan within a simulation environment, and provides seamless interactions between the site layout model and the simulation model. These capabilities facilitate planning construction site layout using simulation by establishing two-way information flows between the site layout and simulation components, which can further promote application of simulation in construction site layout planning. Usefulness and practicality of the proposed DST is demonstrated in site layout planning of a steel erection project.
Conclusions:
Using this DST can reduce some common wastes in construction projects and the cost associated with them, including on-site transportation, material handling and storage, and waiting time for the material arrival.
