BIM-based 3D integrated pipeline design has been implemented in China for many years, but dueto those reasons such as complexities, flexibilities and cross-stages, there is few relevant researches to provideenough reference from design and construction companies. This paper has concluded the experience of adoptingBIM in integrated pipeline design from our company's previous projects, integrated with the case of Zhejiang XindaHospital Project to highlight the Standard Methods and Procedures (SMP) of integrated pipeline design by usingBM based on complex buildings and to summarize the overall process experience of BM based integrated pipelinedesign.
