Regarding the BIM bidding problem in the bidding process of water transportation engineering，a bidding requirement analysis，tool selection，and scheme visualization process research are conducted.Based on the BIM bidding process of a water transportation project，a domestic bidding platform is used to comprehensively integrate the bidding content and publish offline bidding documents.This solves the problems of integrating multiple types of models，integrating multiple source data resources，integrating bidding content and solutions，visualizing solutions，and interactive reporting during the bidding process.Finally，the BIM model is used to complete all bidding work.The conclusion is that the domestically produced bidding platform has obvious advantages in BIM bidding and interactive reporting of water transportation engineering，and can meet the requirements of BIM bidding at the current stage.This study will provide reference and guidance for BIM bidding in similar bidding of water transportation engineering.
