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.

Construction Site Layout

Purpose: This paper aims to develop an efficient model able to reduce catastrophic consequences and the significant number of victims resulting from fires at construction sites. The paper proposes probabilistic modeling aimed to minimize the probability of failure of a construction site. Methodology: The developed model in this paper consists of modeling fire hazards, the vulnerability of the potential targets, and the risk within construction sites. The optimization algorithm called “differential evolution” is used in order to determine the optimal site layout, which is characterized by having the smallest overall probability of failure. A numerical simulation is performed to delineate an appropriate probability density function of the failure of the site. In addition, a geographic information system (GIS) is used to display the spatial variability of fire risk on a construction site. Findings: The paper provides an efficient model to enhance site layout planning and assign locations for supporting temporary facilities at appropriate positions within a construction site. The model is examined through applying it on a simple case study containing numerous facilities. All these facilities are considered vulnerable targets and some of them are potential fire hazards, with different intensity values. Value: Most of the previous research focuses on travel cost distance in developing site layout planning models. This paper fulfills the development of a valuable model able to generate an optimized construction site layout by minimizing the probability of failure of the whole site. It will assist the decision makers and the risk managers in identifying the riskiest zones on a construction site.

In general, construction site management is planning, organizing, leading, directing, monitoring, and controlling overall construction activities, during the implementation phase, one of the key elements of construction site management is site layout planning, which is identifying, sizing, and placing temporary facilities within construction boundaries. It has got enormous influence on project parameters. The main aim of this study is to investigate Erbil’s project’s site layout performance. The study was carried out in Erbil, 16 projects have selected for assessment. From the result, it was found that these projects suffer from poor site layout planning, as there was a poor plan for construction facilities, the location of these facilities was wrong, almost, all projects have neglected safety-related issues and much more factors which have been discussed in the analysis section. As a solution, the researcher believes that the current site layout design of projects need immediate improvement, planning should be considered as priority for every single temporary facility during construction; safety basic should be implemented, including wearing PPE; labor accommodation should be improved; sanitation of the workforce should be good; and many other site layout elements should be developed.
