BIM-Concept for Design of Engineering Networks at the Stage of Urban Planning

Abstract

This study describes a new approach to creating a Central Project Database based on the BIM-concept for designing engineering networks at the stage of urban planning. This approach is based on systematic access to the process of developing urban planning documentation at the pre-design stage of construction. Comprehensive information support of the planning territory corresponds to modern trends in the transition of urban planning to digital construction. An information model of the project of planning territory for construction at the stage of urban design is proposed. The content of each layer of the planning territory information model is described in detail. The conceptual BIM model of spatial data for solving design problems of engineering networks 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 data storage in which operational and external sources supply spatial data and metadata. Block 3 is consumers of information that generate requests for data to the means of presenting the information. The BIM structure of the Central Project Database for comprehensive information support of the design of engineering networks is presented. As the study results are shown, a summary plan of engineering networks was made using BIM-based design software and a digital 3D model of the consolidated plan of engineering networks, made using AutoCAD Civil 3D. The use of BIM-concept at the stage of urban planning design is a new direction of its development. The implication for further research studies on the development of complex BIM-based design for urban infrastructure.
