Irregular Dynamic Site Layout Optimization Model

Abstract

When site space is limited, construction site layout planning plays a critical role in the safety and productivity of all operations. As the construction progresses, dynamic planning for the site layout becomes a need to match the project progress. Proper layout planning should take into account the productivity of operations, minimizing the in-situ travel time, the dynamic nature of site operations, and safety regulations implementation on site. This paper is a continuation of the previous work tackling irregular site layout planning, where it presents a new model approach for optimizing the dynamic planning of site layout with safety consideration. This model’s algorithm shows high performance in tackling complex projects with limited run time compared to other work in literature. The model showcases an automated mapping tool in conjunction with a dynamic scheduling observing safety to produce the optimized site layout using genetic algorithms. To demonstrate the benefits of the proposed model approach, the case study presented in the “Dynamic Layout of Construction Temporary Facilities Considering Safety” paper is taken as the performance reference to verify and validate the model’s output. Examination of the results and the comparative analysis is performed to demonstrate the variance between the outputs of the existing reference model, and this model performed herein.
