The harsh construction environment of breakwater demolition projects determines that construction safety is the primary problem to be solved. Considering the difficulty of construction management in the complex construction environment of breakwater demolition projects，this paper relies on the breakwater demolition project of Tianjin Binhai Information Innovation Base for research on the application of building information modeling（BIM）technology in breakwater demolition projects. Specifically，we use three-dimensional（3D）software such as Revit，Navisworks，and Lumion on the basis of the Autodesk software platform to achieve the rapid creation of the BIM model，3D model rendering and roaming，and demolishing process display of this breakwater project. By the BIM model，the construction progress preview and engineering quantity statistics of the breakwater demolition project are realized，and the application process of BIM technology in breakwater demolition projects is summarized. The research is expected to provide a reference for similar engineering projects.
