Abstract

This study sought to develop a typology model of temporary facility constraints that can be used practically in construction site layout planning (CSLP) automation models. A triangulated methodology (literature review, in-depth interviews, and actual case studies) was used to identify constraints of 11 temporary facilities that are considered mainly in CSLP and to classify them into six constraint types (i.e., dimensional, regional, relocation, non-overlap, inter-facility distance, and visibility constraints) and seven subtypes. In addition, this study proposed computational modeling methods that would allow a computer to judge whether or not the constraints are met by a created construction site layout. This study contributes to CSLP theory by providing a typology model of temporary facilities that can be used in the model-based verification of the created construction site layout and constraint processing condition in CSLP optimization models. This would also help provide efficient, safe, and eco-friendly construction site management, while refraining from experience- and intuition-centered CSLP practices.

Summary

Introduction

Construction site layout planning (CSLP) is one of the important processes that should take place for construction management to be successfully carried out before the commencement of main work. Effective construction site layout contributes to minimizing travel distances, site congestion, time, and efforts required for material handling and transportation, and operational costs [1,2,3], and this, in turn, has a positive effect on the safety, sustainability, scheduling, and cost management of the construction site [4,5,6,7] Despite such importance, CSLP still relies on experience, intuition, and previous construction site layout data. Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations To address this problem, studies on developing automated CSLP models using some optimization algorithms have begun to take place. No attempts have been made to develop a constraint model for use in CSLP automation models through a systematic investigation of the constraints of temporary facilities applied in actual cases
