BIM(建筑信息模型应用)是以三维数字技术为基础,集成了建筑工程项目各种相关工程信息的数据模型,是对工程项目设施实体与功能特性的数字化表达。目前,BIM技术以其优越的数据集成性和信息共享等功能,在我国传统建筑施工中得以广泛探索和应用。各施工企业将以此作为创新发展和提高企业竞争力的重要手段,在促进项目精细化管理、提高工程质量、降低成本和安全风险、优化施工方案、绿 Based on 3D digital technology, BIM (Building Information Modeling Application) is a data model integrating various engineering information of construction projects. It is a digital expression of entity and function features of facilities. At present, BIM technology has been extensively explored and applied in the traditional construction of our country with its superior data integration and information sharing functions. The construction companies will use this as an important means of innovation and development and enhance the competitiveness of enterprises in promoting the refinement of project management, improve project quality, reduce costs and safety risks, optimize the construction program, green
