“…Besides the minimum space required for performing the task, additional safety zone should be allocated to the workspaces in the site layout (Akinci et al 2002). Although the minimum space requirements for different activities are in general known, the shape of their footprint is often more flexible in a 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.

“…Numerous research studies have pointed out the benefits of Building Information Modelling (BIM), especially by using 4D modelling to support production planning and control, such as testing alternative sequences of tasks (Chau et al, 2004), predicting logistics problems (Hartmann et al, 2008), detecting spatial conflicts between tasks (Akinci et al, 2002), monitoring progress discrepancies (Golparvar-Fard et al, 2009), improving site layouts (Ma et al, 2005) and analysing workspace congestion (Chavada et al, 2012). BIM enables a wide range of information to be stored and connected to a virtual building representation, which is produced by different project participants.…”

Managing industrialised construction requires an accurate synchronisation of design, manufacturing and assembly processes. Considering the high uncertainty and the interdependences between different processes on site, it is important to consider the status of the construction site in the planning and control process. Understanding the demands of site assembly in terms of components is a key step for integrating fabrication and site assembly. One possible approach is to use Building Information Modelling (BIM) for planning the logistics operations of prefabricated building systems.The aim of this paper is to describe an application of BIM 4D modelling for supporting the planning and control process of logistics operations for Engineer-toorder (ETO) concrete prefabricated structures. Design Science Research was the methodological approach adopted in this investigation, which involved an empirical study carried out in partnership with a company that design, produces and assemble prefabrication concrete structures. The main contribution of this investigation is on how to increase the reliability of information exchanges by concentrating product and process information in a BIM model. Also, some guidelines on how to plan loading and unloading operations, and how to use BIM to assess changes in production plans, considering the logistics impacts.

“…configured the workspace shape based on 2D plan-view envelops elements. Akinci (2002bAkinci ( , 2002c) generated a 3D workspace model required for the construction of elements and presented the layout methods in an available working area using the generated workspaces. In addition, Tantisevi and Akinci (2007) configured a 3D bounding box model as a moving space with the rotation area of a boom when hoisting materials with equipment, such as a crane.…”

When multiple workspaces for resources are allocated within a narrow work area, the constructability of work may deteriorate based on the conflicts that occur due to the mutual adjacency levels between the workspaces. In this situation, the identification of the workspace overlapping status is essential for establishing the optimized layout planning of workspaces. However, current 3D environments consider only physical collision and reaction by the cross verification of geometric properties to detect collisions between 3D objects. Thus, the configuration of methodology to visually check the overlapping level of workspaces with conflicting status is insufficient for a successful interference management. This study develops a new grid cell-based analysis algorithm and its 4D simulation system for visually verifying the workspace overlapping of dynamic resources to be allocated multiply within a confined area, such as a tunnel or underground facility. The proposed algorithm and system can assist in the intensive management of activities that have a high level of workspace overlap by visualizing their overlapping level.
