摘要:近年来，我国建筑业掀起了一场基于信息化变革的热潮，“BIM技术”在其中扮演了最为重要的角色。它不仅可以从技术上实现碰撞检查、虚拟施工等项目可视化应用；又可以从经济上实现合约规划、短周期多算对比等关联信息库应用。然而，过分夸张的宣传、不切实际的思想、水土不服的软件使“BIM技术”越来越神秘，离真实也越来越远。可是“BIM技术”作为建筑业革命性技术的功绩依然不可磨灭，它对传统的工作方式进行优化，对低下的工作效率进行提升，对粗放的生产方式进行精细化改造，真正实现基于BIM的“设计-合约-施工”一体化工作流(即“DCC-BIM”)。BIM在一体化工作流中根据各阶段的相应要求，按照一定的标准和规范进行元素重构，使BIM应用主体在某一阶段的发挥巨大的实质性价值。同样，“BIM技术”与互联网、云计算、点云、无限射频、3D打印等技术的结合必定在未来的智慧城市建设中发挥不可估量的作用。

Abstract: In recent years, China's construction industry set off a boom based on information revolution, in which "BIM technology" has played the most important role. It can not only realize visualization applications such as collision check and virtual construction projects but also related information database applications such as economic contract planning, short cycle multi-count contrast. However, exaggerated propaganda, unrealistic thoughts and unacclimatized software makes the "BIM technology" more and more mysterious and distant from the truth. But as a revolutionary technology of the construction industry, the achievements of "BIM technology" can never be neglected. It can optimize traditional working modes, improve working efficiency, carry out fine reformation of the extensive production mode, and realize BIM-based integration workflow of "design-contract-construction" (DCC-BIM). According to requirements of each stage of the integration workflow, BIM reconstructs elements based on certain standards and codes, and thus BIM application body plays a substantive value at a certain stage. Similarly, the combination of BIM technology with technologies such internet, cloud computing, point cloud, radio frequency and 3D printing would certainly play an invaluable role in the future smart city construction.
