Development Trend of Water Supply and Drainage Engineering Based on Life Cycle Assessment and Building Information Model

With the rapid development of construction engineering and municipal engineering in recent years, water supply and drainage technology has gradually matured. Building water supply and drainage design contains the design of rainwater drainage, sewage drainage design, water supply design and fire water supply design. At present, the research on the life cycle assessment of urban drainage system is mainly focused on the sewage treatment plant, therefore in this paper we introduce the theoretical basis of life cycle assessment. In the era of information network, building information model (BIM) technology is widely applied to the design of building water supply and drainage, which and effectively improves the design efficiency, and makes up for the traditional water supply and drainage design of a lot of problems. In this paper, we analyze the development trend of water supply and drainage engineering based on life cycle assessment and building information model.
