In view of issues such as the numerous parties involved in the design and construction of underground pipeline，the difficulty of coordination，the tedious project management control，and frequent design changes，BIM technology can accurately and intuitively display the whole view of the pipeline network，and help contractor respond to change requirement timely so as to review the quantity rapidly，track construction progress and quality in real-time，improve the efficiency of technical disclosure and completion acceptance. In this paper，the underground pipeline project of Posorja Multi-Purpose Terminal in Ecuador is introduced for elaborating the BIM technology application in design and construction，fully demonstrating the intuitiveness，intelligence，efficiency，and synergy.
