METHODOLOGY OF BUILDING INFORMATION MODELING OF URBAN STREETS AND ROADS

Problem statement. New challenges in road construction require the application of modern and globally recognized best practices in the design and management of road infrastructure construction processes, involving the use of the latest Building Information Modeling (BIM) technologies. The implementation of BIM technologies necessitates conducting research to systematize information, forecast and evaluate outcomes, and develop a modeling methodology. The purpose of the article is to develop a methodology for Building Information Modeling of urban streets and roads. Research Results. The proposed methodology for Building Information Modeling is demonstrated using sections of the street and road network in the city of Dnipro. Digital terrain and site models were created in the InfraWorks software based on geospatial data from remote sensing. Conceptual models of urban streets and roads were developed. The conceptual models were exported to Civil 3D, where the terrain model was refined using ground survey data, analyzed, and used to develop route plans, longitudinal and cross profiles of streets and roads. The detailed and coordinated road design solutions in Civil 3D were exported to InfraWorks to build an integrated road infrastructure. An analysis of the spatial smoothness of routes and sight distances on roads was conducted using the building information model. Models of an overpass and bridge developed in Revit were exported to the road infrastructure model. Traffic management measures were modeled. Using the “Traffic Simulation” tools in InfraWorks, vehicle traffic flows on roads and interchanges of the studied street and road network were simulated, taking into account the actual traffic intensity. The building information models were checked for structural deficiencies using Navisworks software. Conclusion. The proposed methodology for designing urban streets and roads using BIM technology involves the step-by-step development of a digital model utilizing software for the automated design of road infrastructure with the required level of detail at each stage of the design process.
