本文首先对BIM技术的基本概念及其在建筑给排水设计环节中的应用优势进行分析,然后从协同设计、可视化设计、管道综合设计、以及材料表统计这四个方面入手,分析在建筑给排水设计中应用BIM技术主要内容,最后结合某建筑室内卫生间给水系统设计实例,分析应用BIM技术进行给水方案设计的步骤与应用要点,望能够通过对BIM技术的灵活应用,以起到提高建筑给排水设计质量及水平的目的。 This article first analyzes the basic concept of BIM technology and its application advantages in the design of building water supply and drainage. Then from the four aspects of collaborative design, visual design, integrated pipeline design and material list statistics, In the end, the main contents of BIM technology are applied in the design. Finally, combining with the design example of a bathroom interior water supply system in a building, the steps and application points of BIM technology in water supply scheme design are analyzed. It is hoped that through the flexible application of BIM technology, Design quality and level of purpose.
