Aiming at the problems of large project volume，difficult construction and large engineering error during construction of high-piled wharf，this paper carries out a research on the application of BIM technology to the construction of hydraulic docks. The application of BIM technology to the construction visualization，collision inspection，engineering quantity calculation，and construction organization design achieves remarkable effect in the construction quality，schedule and cost control of the high-piled wharf project. It may serve as reference for the practical application of BIM technology to the construction of the high-piled wharfs hydraulic engineering.
