摘要:通过借助天津市规划局委托设计院进行天津文化中心区的城市综合设计工作，大胆尝试了在该项目中建立UIM的工作理念，即建构“城市信息模型”数字城市; 把BIM设计与应用从单体建筑、群体建筑外延扩大到区域、城市规划，使城市综合设计工作真正从BIM应用阶段拓展到UIM领域; 提出了UIM平台数据库的意义、建设原则、UIM信息模型以及数字城市工作任务书等; 本文旨在提出数字城市总体设想和研究框架思路，具体设计与研究正在分阶段、分任务进行; 深切感到UIM平台建立的重大意义，希望通过实践，最终使BIM的优势应用到城市设计与前期工作，为城市的数字化建设作出贡献。

Abstract: By means of Tianjin, Tianjin Planning Bureau commissioned the Institute for Cultural Center of the city's comprehensive design work, we have a bold attempt to establish UIM in the project work ethic, that construct "Urban Information Model" digital city. The design and application of BIM from single building, community outreach to expand to the regional architecture, urban planning, the city's comprehensive design work truly BIM application stage expanded to UIM fields. We propose UIM-platform database meaning construction principles, UIM information model and task books and other digital city, digital city paper aims to propose the framework of the overall vision and research ideas, specific design and research is being phased, task, we deeply feel UIM platform to build the significance and hope that through practice, and finally to the advantage of BIM applied to urban design and preliminary work for the construction of digital cities to contribute.
