“…Planning and design of a construction projects are the foundation of successful construction projects and play a major impact on sustainable land usage [54,55]. However, site space, as a typical construction resource, tends to be additionally important to the sustainability of construction land usage [56] for its impacts on work efficiency, material, and travel distance [57,58]. Therefore, many specifications or regulations, such as the Green Construction Guideline (GCG) and the Code for Green Construction of Building (CGCB) issued by MHURD in 2007 and 2014, respectively, dictated that the special program for land use on construction site should be compiled [59,60].…”

On-site construction stage has been considered as the key in practicing the view of green construction. Moreover, the unity of awareness and actions of on-site contractors on green construction plays a conclusive role through the implementation of green principles on the construction site. This study aims to investigate the awareness on green construction and to identify the gaps between the awareness and activities in adopting green specifications from the perspective of on-site personnel. A questionnaire survey was conducted with on-site personnel in Mainland China for identifying the gaps between the awareness and activities in the adoption of green construction. The results show that the level of awareness on a certain green requirement is higher than the performance of implementation. Nine groups with large gaps between awareness and activities are identified. Activities about pumping groundwater, burning wooden scraps, preventing strong light, reducing construction sound and noise, adopting green material, optimizing material plan, adopting water recycling devices, and employing energy efficiency machine cannot support high green construction awareness. Moreover, the "utilization of natural resources on-site" has the lowest performance with both low level of awareness and activities. This paper also suggests some useful implications for governments and departments of construction administrations to take measures in ensuring the thorough implementation of green activities on the construction site.

“…Despite the recognition in literature of the importance and impact of the efficiency of access roads (Handa and Lang 1988;Mawdesley et al 2002;El-Rayes and Khalafallah 2005;Sanad et al 2008), the planning of access roads has not yet been addressed in the research to date. The inclusion of access roads in modeling site layouts is important as they define the travel distance between objects -a measure that is often used for the optimality of a generated layout.…”

Abstract:The efficient planning of site space through the course of a construction project is referred to as site layout planning. Due to its impact on safety, productivity and security on construction sites, several site layout planning models have been developed in the past decades. These models have the common aim of generating best layouts considering the defined constraints and conditions. However, the underlying assumptions that were made during the development of these models seem disparate and often implicit. This study provides an overview of the existing models and aims to draw a holistic view of variables that have been considered at different levels of detail and using different approaches in the site layout literature. Through close examination and comparative analysis of existing models, this study identifies the components that need to be considered for site layout modeling, referred to as constructs. Possible approaches that can be used to realize each construct are presented, and the advantages and disadvantages of these approaches are discussed. It is hoped that this study contributes to a better understanding of site layout modeling, and provide an outline for the development of new site layout planning models.Key words: construction site planning, site layout modeling, modeling constructs, site management, optimization models.Résumé : La planification de l'agencement d'un espace défini dans le cadre d'un chantier de construction est appelée « plan d'aménagement de site ». En raison de l'impact de ce dernier sur la sécurité, la productivité et la sûreté des sites de construction, de nombreux modèles de plans d'aménagement de site ont été développés au cours des dernières décennies. Ces modèles ont pour objectif commun de concevoir des aménagements optimaux en tenant compte de contraintes et de conditions précises. Cependant, les hypothèses de base émises lors de l'élaboration de ces modèles semblent nombreuses et souvent implicites. La présente étude fournit un aperçu des modèles existants et a pour but d'offrir une vision globale des variables qui ont été étudiées à différents niveaux de détail et sous diverses approches dans la littérature traitant de l'aménagement de site. Grâce à un examen attentif et à une analyse comparative des modèles existants, le présent article identifie les composants, nommés « structures », à prendre en compte dans la modélisation de l'aménagement de site. L'article décrit également les différentes approches pouvant être adoptées pour créer chaque structure ainsi que les avantages et désavantages de ces approches. Il est à espérer que la présente étude contribuera à une meilleure compréhension de la modélisation de l'aménagement de site et constituera un point de départ à l'élaboration de nouveaux modèles de plans d'aménagement de site.

“…If any of the requirements are changed during construction work, the site layout of the temporary facilities should be changed, accordingly. Studies in which the problem was considered dynamically are Ning et al [23] and Sanad et al [24]. Souein & Tommelein [25] presented an algorithm that calculated a solution gradually with the stage of construction by combining the heuristic method and the linear planning method.…”

“…El-Rayes et al [27] presented a multi-object optimization model for minimizing transport cost and maximizing safety using GA, and Sanad et al [24] dealt with the site layout problem using GA after reflecting safety and environmental problems in the object function. Ning et al [15] reviewed multi-object optimization considering safety and the environment as separate object functions.…”

Determining the layout of temporary facilities that support construction activities at a site is an important planning activity, as layout can significantly affect cost, quality of work, safety, and other aspects of the project. The construction site layout problem involves difficult combinatorial optimization. Recently, various artificial intelligence(AI)-based algorithms have been applied to solving many complex optimization problems, including neural networks(NN), genetic algorithms(GA), and swarm intelligence(SI) which relates to the collective behavior of social systems such as honey bees and birds. This study proposes a site facility layout optimization algorithm based on self-organizing maps(SOM). Computational experiments are carried out to justify the efficiency of the proposed method and compare it with particle swarm optimization(PSO). The results show that the proposed algorithm can be efficiently employed to solve the problem of site layout.
