BIM-Based and Augmented Reality Combined with a Real-Time Fire Evacuation System in the Construction Project

Abstract

Typically, the fire evacuation plan used in construction projects is represented in two-dimensional (2-D) drawings that cannot identify the current worker’s location and cannot display the evacuation route in real-time. Thus, when fires occur, the damages can be found in the construction project's fire and the number of dead or injured workers involved in the cases. Nowadays, the technologies of Building Information Modeling (BIM) and Augmented Reality (AR) are used in construction projects to create construction drawings and display the physical characteristics of construction projects in a three-dimensional (3-D) visualization. This study aims to propose and demonstrate the use of Building Information Modeling (BIM) and Augmented Reality (AR) technologies to develop a prototype of a BIM-based and Augmented Reality (AR) in combination with a real-time fire evacuation system to process and display accurate information to workers. This study was conducted to test the accuracy of information obtained from a prototype system at the Department of Civil Engineering building, Faculty of Engineering, Chulalongkorn University. The distance of the building was measured from a prototype system. Then, the data was analyzed for error compared to the MATALL MT-LM100 laser distance meter. The results showed that the data from the prototype system error was less than 6%. This study proved that a BIM-based and Augmented Reality (AR) prototype combined with a real-time fire evacuation system could accurately evaluate and display fire evacuation information to workers.
