Given the shortcomings of the traditional high-piled wharf two-dimensional design process，combined with the practical application of BIM technology in Yancheng Port’s heavy-duty wharf project，this paper elaborates the BIM collaborative design method from three aspects：collaborative server construction，family library construction，and multi-disciplinary collaboration，and puts forward the application points of BIM design stage of component parameterized design，detailed statistics of engineering quantities，parameterized design of complex nodes，and standardization of engineering drawings. Studies have shown that the application of BIM technology has realized the linkage and sharing of model element information，and has improved the participation of multi-disciplinary collaboration，and the accuracy of engineering design expression and collaboration efficiency have also been improved.
