“…This cooperation is bolstered by several uses defined throughout academic literature [28,29]. Those uses allow professionals to analyse a construction site during its preparation as well as during its progress, according to both a process and resources point of view [30]. An emphasis is placed on predictive analysis, which seems to be lacking in the usual practices of the industry [28,29].…”

“…Furthermore, it should be noted that 4D BIM mainly considers the temporal evolution of the site, while neglecting its spatial evolution: i.e. operations are optimized solely by comparing schedules [30,31]. However, a 4D BIM model can also include resources and their flows to represent the site's evolution [27,[29][30][31].…”

The construction industry is changing its practices to adapt to its contemporary context. The rise of Building Information Modelling (BIM) is disrupting the way a construction project is thought and managed. To support this evolution, inspiration is taken from manufacturing industries practices which have faced similar challenges. The goal is to develop a more industrialized way to build in order to better manage quality, costs, delays, and to improve working conditions. This article develops the main challenges to face so to achieve this transformation through a literature review. BIM can be compared to the Product Lifecycle Management (PLM) system in manufacturing fields. BIM could be further developed by changing its unique data structuring into a PLM-inspired organization to adapt representation to the project's stages and stakeholders needs. Data management also allows more detailed simulations of site operations, highlighting the current planning practices limits. Finally, developing a data-centered approach to manage and produce facilitates early and cross-disciplinary cooperation. This reorganization supports the application of heterodox production methods like off-site construction. As a whole, industrializing construction demands to develop a holistic vision of a facility lifecycle, which can only be developed through better communication and more collaborative practices, bolstered by a more developed digital model.

“…BIM can be defined as a set of tools, processes and technologies that are enabled by a digital representation of the physical and functional characteristics of a built asset (Sacks et al, 2018) expressed in data-enriched 3D models and their relationships. This digital replica constitutes a shared and central source of data about a facility, forming a reliable basis to produce information that supports insightful decision making for planning and managing a construction project during its whole life cycle (Dashti et al, 2021). Such information could include onsite spatial and topographical information, temporal and schedule information, and resources and cost information, among others (Popov et al, 2010;Moon et al, 2014;Bortolini et al, 2019).…”

Building Information Modelling (BIM) can be defined as a set of tools, processes and technologies that are enabled by a digital multi-dimensional representation of the physical and functional characteristics of a built asset. The ‘fourth’ dimension (4D BIM) incorporates time-related project information in the 3D model to simulate and optimise the project construction process. To achieve this, the 3D objects within the aggregated design model must be linked with each activity in the construction schedule. However, the levels of maturity and expertise in using BIM amongst the project participants still varies considerably. This generates collaboration problems within the project and adds further obstacles to the ability to derive full benefits from BIM. Ideally, 4D BIM can be automatically generated, but in reality, because the 3D and 4D models are created separately and at different stages of the project, this is not currently possible, and the process requires considerable manual effort. The research reported in this paper was prompted by the construction of a new training and research building: the Nanterre 2 CESI building in France. It proposes an efficient approach that minimises the effort of creating 4D BIM construction schedules. The CESI four-phase process aims to help project participants to fully exploit the potential of 4D BIM and enables: 1) a clear expression of the 4D BIM objectives; 2) the identification of information requirements and relevant workflows to achieve these objectives; 3) the implementation of a project schedule; and 4) BIM model production to suit the 4D BIM use case. Although the CESI approach was developed in the context of the French contracting system, the observations and conclusions of this study are intended to be generally applicable.

“…The severity of interference is calculated by dividing the overlapped duration by the activity duration. Dashti et al [16] proposed a 4D BIM-based simulation model for automatic management of time-space conflicts in the pre-construction planning phase. This model enables the practitioners to detect all types of possible time-space conflicts automatically.…”

Space-Constrained Scheduling Optimization Method for Minimizing the Effects of Stacking of Trades

2021

Existing SCS (space-constrained scheduling) studies fall short of minimizing the effect of the stacking of trades that decline productivity due to an increase in resources within a physically limited work area. This article presents a space-constrained scheduling optimization (i.e., SSO) method for minimizing the stacking of trades. It imports schedule information from the project database, extracts IFC files of construction site area from the BIM model, defines the occupation density function of each activity to track the level of stacking of trades, and identifies the optimal solution (i.e., the optimal set of pairs of execution pattern alternatives and start times of activities) by implementing genetic algorithm (GA) optimization analysis. The study is of value to practitioners because SSO provides an easy-to-use computerized tool that reduces the lengthy computations relative to data processing and GAs. Test cases verify the validity of the computational method.
