The gulf regulation project is a new marine industry in recent years. In view of the characteristics of the complex topography，many professional types，many design drawings and many professional cross sections in the design process of the gulf regulation project，we carry out the design and management of the gulf regulation project based on BIM collaborative platform. Building BIM collaborative platform and utilizing the advantages of BIM’s visualization and synergy to aid the design management，we solve the problems caused by the above characteristics，and draw the conclusion as follows：based on the collaborative platform，we can carry out multi-specialty meeting and examination，synthesize coordination，optimize design，improve design efficiency and quality greatly，and establish the design management database to provide a basis for the later decision-making of similar projects；due to the visualization of BIM，the surrounding environment of the project is incorporated into design to assist the space validation and type selection.
