Comprehensive Information Support of Urban Planning on BIM-based Design

Abstract

The article is devoted to comprehensive information support of urban planning design based on BIM-technology. The study is based on a systematic approach to the process of developing urban planning documentation at the pre-design stage of construction, based on the current modern trend of transition to the digital economy. Information model of the territorial cluster of urban planning design is proposed in the study. The content of each layer of territorial cluster information model is described in detail. The conceptual model of spatial data storage for solving problems of general planning of the territorial cluster is presented in the form of three main blocks. Block 1 is data sources that are taken from the operating system and external sources. Block 2 is a data store, which operational and external sources supply spatial data or metadata. Block 3 is consumers of information that generate requests for data to the means of presenting information. The structure of Unified Information Support Center (UISC) and performers for comprehensive information support of the territorial cluster is presented in the study. As the results of the study are shown summary plan of engineering networks, made using BIM-based design software and digital 3D model of the consolidated plan of engineering networks, made using AutoCAD Civil 3D. The use of BIM technologies at the stage of urban planning design is a new direction of its development.
