“…The study concluded that it is feasible to incorporate a fire alert system into BIM as an efficient and useful way to detect fires and notify the building's occupants. Lotfi et al (2021) examined a high-rise building to assess the feasibility of providing a safe evacuation environment for its occupants under post-earthquake fires. BIM and PyroSim simulation software were used to create a 3D model of the building to measure the escape routes, smoke and fire developments.…”

Purpose This paper aims to present a systematic review of the published literature on building information model (BIM)-based simulation tools used for occupant evacuation over the past 23 years. Design/methodology/approach A literature review was conducted on BIM-based simulation tools used for occupant evacuation over the past 23 years. The search identified a total of 37 relevant papers, which were reviewed. The paper describes the use of BIM-based simulation tools over the years and identifies the research gaps. Findings BIM-based simulation tools have undergone progressive development, with constant improvements through the integration of advanced tools and collection of more data. These tools can assist in identifying faults in the building design. The outcomes of the simulation were not entirely accurate, as real-life scenarios vary depending on the various building types and the behavior of their occupants. Research limitations/implications This study contributes to the literature through reviewing the capabilities of BIM-based simulation tools and the different simulation methods along with their limitations. Practical implications Fire safety engineers and architects can comprehend the utilization of BIM-based simulation tools to enhance the fire evacuation in light of their shortcomings and flaws. Originality/value BIM-based simulation tools are becoming more advanced and widely used. There has not been a comprehensive evaluation of the capabilities of the integration of BIM tools and simulation modeling for occupant evacuation. This study guides researchers on the capabilities and efficiencies of integrated solutions for occupant evacuations and their inherent shortcomings. The study identifies future research areas in BIM-based tools for occupant evacuation.

“…The BIM platform can also be integrated with fire simulation software to simulate real-time fire growth [32] and to calculate the available safety egress time [33], which is the duration during which the fire creates fatal environmental conditions and within which time the people are required to evacuate a building in order to ensure safety. For instance, Wang et al [34] integrated a 3D building model developed in Revit into the PyroSim fire simulator.…”

Platform Development of BIM-Based Fire Safety Management System Considering the Construction Site

et al. 2022

Fire at a construction site usually results in serious accidents. Therefore, fire management at the construction site is critical to decreasing possible accidents. However, conventional fire safety management can be problematic in many aspects, such as visualization, multi-stage alarm systems, and dynamic escape route optimization. To solve these issues, this paper develops a platform for a BIM-based fire safety management system that considers the construction site. The developed platform contains four subsystems: a remote monitoring subsystem, a fire visualization subsystem, a multi-stage fire alarm subsystem, and an escape route optimization subsystem. It detects the fire hazard in the early stage of the fire by the remote monitoring subsystem and transmits this information to the fire visualization subsystem for displaying. Furthermore, the multi-stage fire alarm subsystem sends warnings or alarms based on the fire’s severity. Moreover, the escape route optimization subsystem dynamically optimizes the evacuation routes by considering the actual number of people at the construction site and the potential crowding as people pass through the escapeway. Results show that this system can provide informative and on-time fire protection measures to different participants at the construction site. This study can also serve as a solution to improve fire safety management at the construction site.

“…Optical 3D scanning shows a growing trend in the construction industry, providing a complete and consistent building engineering database by establishing a virtual building 3D model based on digital technology. Nowadays, Building Information Modeling (BIM), as a key application of optical 3D scanning, dominates project follow-up, building monitoring, and maintenance [1][2][3][4], architecture planning [5][6][7][8], emergency simulation [9][10][11][12], and IoT [13][14][15][16]. Implementing BIM methods helps improve the efficiency and integration of constructions in all stages of their life-cycle, as well as helps provide a platform for engineering information exchange and communication [17][18][19][20].…”

Point Cloud Registration contributes a lot to measuring, monitoring, and simulating in building information modeling (BIM). In BIM applications, the robustness and generalization of point cloud features are particularly important due to the huge differences in sampling environments. We notice two possible factors that may lead to poor generalization, the normal ambiguity of boundaries on hard edges leading to less accuracy in transformation; and the fact that existing methods focus on spatial transformation accuracy, leaving the advantages of feature matching unaddressed. In this work, we propose a boundary-encouraging local frame reference, the PyramidFeature(PMD), consisting of point-level, line-level, and mesh-level information to extract a more generalizing and continuous point cloud feature to encourage the knowledge of boundaries to overcome the normal ambiguity. Furthermore, instead of registration guided by spatial transformation accuracy alone, we suggest another supervision to extract consistent hybrid features. A large number of experiments have demonstrated the superiority of our PyramidNet (PMDNet), especially when the training (ModelNet40) and testing (BIM) sets are very different, PMDNet still achieves very high scalability.
