Abstract: In view of the shortcomings of the traditional fire monitoring and early warning mode of subway projects under construction, such as low visualization degree and complicated information management, this paper proposes a visual management mode of fire monitoring and early warning combined with BIM Technology.In this way, BIM model is used as the carrier, and through the use of RevitAPI secondary development technology, the fire monitoring information is classified and integrated according to the function and order, and a "fire alarm platform" with visual early warning, data viewing, information analysis and information sharing function modules is built on Revit platform to further improve the interaction between monitoring information and BIM model, and optimize the fire monitoring early warning function visual management level, improve the safety factor of subway construction. A station of Nanning Metro Line 3 is taken as an example to analyze the practicability of this method. The practice shows that this method can improve the visual management level of fire monitoring and early warning, and has certain practical significance and application value.

Key words: subway construction, fire monitoring and early warning, visualization
