Architecture Engineering and Science

This paper studies the application of BIM technology in the design of building water supply and drainage system, and puts forward the strategy of data acquisition and analysis, system simulation and evaluation and design optimization based on BIM. Through BIM technology, the building water supply and drainage system can realize data integration, visual management and control, and improve the design accuracy and construction efficiency. At the same time, BIM technology also supports the simulation and performance evaluation of water supply and drainage systems, helping to identify potential problems and optimize design solutions. In addition, this paper also discusses the development trend of BIM technology in building water supply and drainage design, and puts forward future research directions and key suggestions, emphasizing the important role of BIM technology in improving design quality and efficiency, reducing operating costs and promoting building sustainability.
