本文提出BIM的本质是功能参数广泛集成的数字化模型,属于技术领域的信息化,纠正了当前BIM实践中将BIM混淆于全部信息化的倾向。结合美国公路领域的BIM应用经验,将BIM应用划分为模型应用与集成应用两个层次,并明确了BIM平台与其它平台的区别和联系。在此基础上,对深中通道项目的信息化做出总体规划,明确了BIM+MIS并适当集成的结构,最后将深中通道协同工作平台规划为包含BIM模型在内的文档协同平台与工程数据为主的管理平台两部分。 This paper proposes that the essence of BIM is the digital model with extensive integration of functional parameters, which belongs to the information technology in the technical field, and correct the tendency that BIM confuses all the information in the current BIM practice. Combined with the experience of BIM application in the field of highway in the United States, the BIM application is divided into two levels: application of model and application of integration, and the difference and connection between BIM platform and other platforms are clarified. On this basis, the overall plan for the informatization of Shenzhen-Zhongdao project is made, the structure of BIM + MIS and its proper integration are defined, and finally, the planning of the collaborative work platform for the middle-deep channel as a document collaboration platform and project including BIM model Data-based management platform in two parts.
