“…Some of the developed tools are low tech, while some others use more advanced technologies. In the first category, there are the tools based on Microsoft Excel [24] provided by [25,26]. Although the use of a widespread tool like Microsoft Excel enables all construction practitioners to apply this approach, 2D spatial representation may represent a limitation and cause failures in the detection of spatial interferences.…”

In the architecture, engineering and construction (AEC) industry, many efforts have provided remarkable contributions to construction planning and control processes during work execution. Nevertheless, frequent coordination issues among stakeholders and difficulties in dealing with unexpected events can be explained by the complexity featuring the construction sector. Several approaches to deal with this issue were investigated in the manufacturing area, among which this paper looks at the holonic approach as one of the most promising strategies. This study first analyzes the more fragmented and dynamic nature of the construction industry as compared with the manufacturing one. Secondly, it suggests developing a process-based holonic construction management system based on building information modeling (BIM) and a conceptual architecture for manufacturing control called Product Resource Order Staff Architecture (PROSA). The process-based paradigm ensures exploiting the benefits of BIM towards the development of sustainable and efficient regeneration methods of the built environment. Subsequently, a first management system prototype was developed and tested for the purpose of renovation works management. For the first time, results from an actual implementation of PROSA were applied to a real construction site, and its feasibility was assessed using the data on the field. Key performance indicators (KPIs) evaluated during the onsite demonstration confirmed a good performance of PROSA and the presented holonic approach, which contributed to the overall success of the energy efficient refurbishment project.

“…The mission of design science is to develop knowledge that the professionals of the discipline in question can use to design solutions for their field problems ( Van and Joan, 2005). Based on procedural methodologies and spatiotemporal chronographic modelling (Francis, 2004;2016;2020), these models will allow the calculation and anticipation of spatiotemporal occupancy rates of construction sites and use it as a leveling factor to ensure optimal utilization of available indoor and outdoor spaces during the planification phase. The aim is to create and analyze the dynamic model of the occupancy rate schedule and identify over-and underutilized sectors.…”

The new trend in planning building projects involves incorporating space management on the construction site. Failing to consider the management of site operations can lead to either relaxed or congested construction sites. This is because labor, tools, equipment, and materials all require space. It is important to plan for the circulation and temporary storage of materials, including recycling, reuse, and disposal. Temporary installations and finished products also take up space and can impact traffic flow. For example, partitions can impair traffic flow, while finished flooring can restrict it. The occupation of spaces also changes as the work progresses, so it is important to monitor and accommodate these changes. Therefore, space management needs to be coordinated throughout the construction phase. Traditional planning methods do not consider the analysis of critical spaces or their evolution over time. As a result, they produce schedules that do not reflect the reality of the construction site. Dynamic space-time planning means modelling the operational flow in different sectors of the construction site to optimize the construction process. Efficient space occupation allows for more effective utilization of available resources. This paper aims to analyze the spatial requirements of various construction operations and develop standardized artifacts that integrate spatial information into the schedule. To achieve this objective, the methodology aims to: (i) Conduct site surveys to collect data and analyze construction operations and their spatial needs; (ii) Define the necessary parameters for determining the occupancy rate (OR); (iii) Develop the needed artifacts for representing the static models based on the survey results and the developed occupancy parameters to visually depict and compute various types of occupancy and operations; (iv) Conduct workshops with the professionals in the construction industry. The participants were asked to provide feedback on whether the artifacts effectively captured the various aspects of construction work, such as equipment, tools, materials, and safety protocols. The aim is to validate that the artifacts as reliable representations of real-life construction scenarios. The feedback and input provided by the professionals helped to ensure that the artifacts were accurate, informative, and valuable for training purposes in the construction industry.

“…It becomes static or plane planning when the use of time or space is ignored. Such separations are likely to cause potential time or space conflicts of construction activities, leading to various challenges such as safety, quality, delivery, and cost [3] [4]. For those reasons, the organization and control of construction activities from the perspective of the use of both time and space, namely spatiotemporal planning, has been gradually valued in recent years because it effectively integrates both of them [5][6] [7].…”

Designing a reasonable and efficient transportation system of temporary elevators from the perspective of spatio-temporal planning is beneficial for the successful completion of construction projects. Specifically, the determination of the service period and floor of temporary elevators and the consideration of the limited availability of time and space should be taken seriously. The spatio-temporal planning of temporary elevators puts forward higher requirements for the display of planning solutions due to the complexity considering both time and space. However, current display ways are generally abstract, low-dimensional, and static, and even when the 4D model is adopted, the display effect of spatio-temporal planning solutions is still limited. This research presents a spatio-temporal planning simulation of temporary elevators in construction using a game engine to address those challenges. The workflow of the spatio-temporal planning simulation divided into configuration and operation planning consists of three steps: 1) import data into the game engine platform, 2) generate the spatio-temporal planning simulation scheme, and 3) conduct the spatio-temporal planning simulation. The results of the experimental test show that the presented spatio-temporal planning simulation way is intuitive and convenient, various planning elements are clearly shown, and corresponding planning information is efficiently conveyed, which can effectively enhance the display effect of spatio-temporal planning solutions.
