“…Efforts are being made to standardize the data to improve the accuracy of the simulations. The type of fire, smoke propagation and the amount of fire escape routes also impacts the evacuation time along with the structural design of the building itself (Wu et al , 2015). The type of materials used inside the building along with the present fire load inside the building will also play a crucial role during an emergency fire evacuation.…”

“…There are several factors that hinder obtaining accurate simulation results. These factors focus mainly on modeling occupants’ behavior, as it is volatile and hard to predict (Clever et al , 2022), the severity of the fire (Menzemer et al , 2022), smoke propagation and fire spread, which will impact the occupants’ behavior (Wu et al , 2015). Since the development and wide scale adoption of simulation models, BIM-based tools have been used to study fire evacuation to improve the evacuation efficiently and highlight any deficiencies of the building during an emergency egress (Tan et al , 2015).…”

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.

“…Although, the possible interactions, the building model is currently mostly used for visualization purposes. Wu et al [9] proposed a system for data interchange between BIM and CFAST (Consolidated Model of Fire and Smoke Transport). After the simulation, simulation results are brought back into the BIM module for visualization.…”

This paper presents an outline for improved localization and situational awareness in fire emergency situations based on semantic technology and computer vision techniques. The novelty of our methodology lies in the semantic linking of video object recognition results from visual and thermal cameras with Building Information Models (BIM). The current limitations and possibilities of certain building information streams in the context of fire safety or fire incident management are addressed in this paper. Furthermore, our data management tools match higher-level semantic metadata descriptors of BIM and deep-learning based visual object recognition and classification networks. Based on these matches, estimations can be generated of camera, objects and event positions in the BIM model, transforming it from a static source of information into a rich, dynamic data provider. Previous work has already investigated the possibilities to link BIM and lowcost point sensors for fireground understanding, but these approaches did not take into account the benefits of video analysis and recent developments in semantics and feature learning research. Finally, the strengths of the proposed approach compared to the state-of-the-art is its (semi-)automatic workflow, generic and modular setup and multi-modal strategy, which allows to automatically create situational awareness, to improve localization and to facilitate the overall fire understanding.

We introduce an open-source software Aamks for fire risk assessment. This article focuses on a component of Aamks -an evacuation simulator named a-evac. A-evac models evacuation of humans in the fire environment produced by CFAST fire simulator. In the article we discuss the probabilistic evacuation approach, automatic planning of exit routes, the interactions amongst the moving evacuees and the impact of smoke on the humans. The results consist of risk values based on FED, F-N curves and evacuation animations.
