Research On Management Platform Of Expressway Construction Period Based On BIM Technology

With the continuous advancement of our country’s highway construction,its management work has become increasingly complex and arduous.In the new era of rapid development of digitization and informatization,the traditional mode of construction and management of highway projects relying on two-dimensional information can no longer meet the needs of smart transportation construction.In order to achieve effective management of expressway projects,the application of Building Information Modeling(BIM)technology has become an inevitable trend.It has important practical significance to promote "standardized construction",the organic integration of modern management and traditional construction management,and the integration of information and intelligent management in highway construction and supervision.In this thsis,the expressway component-level information model coding was compiled.Revit was used to create the highway BIM standard component library model.Besides,the business management and control methods during the highway construction period were studied.The highway engineering construction management system was developed,and its feasibility and practicability for model information integration and business management in the highway management platform were verified.Finally,research and discuss the standards for the creation and delivery of the expressway delivery model.The main research contents are as follows:(1)Based on the highway information model,the research on component-level classification,coding and information storage is carried out.This combines the characteristics of highway engineering and is based on the classification framework recommended by international standards for construction engineering and existing coding standards.This research serves the realization of information binding,extraction and use functions of the highway management platform model.(2)The reusable parametric highway standard component library model was successfully created,which made up for the lack of "system family files" such as doors and windows in the existing Revit software in the field of highway construction,and realized the rapid construction of BIM models.In addition,the application effects of the component library model were demonstrated one by one.(3)The key technologies for the integration of BIM and GIS,as well as highway business management methods and system development technologies driven by BIM have been studied.A highway BIM management platform has been established,including two sub-platforms,a BIM information model visualization platform and a construction management and control platform.The usability and effect of the coding,component library,and BIM management method built in this paper on the expressway construction management platform were verified via an expressway example.(4)The BIM model is the digital carrier of engineering information in the highway construction management system.This article discusses the delivery standards that the model should meet in the management system after the highway completion acceptance from the three aspects of model fineness,geometric expression accuracy and information granularity.The BIM model of a certain expressway completed and delivered is used for display and explanation.
