Development Of Road Construction Management System Based On BIM+GIS

With the rapid development of social economy,road infrastructure construction has also developed rapidly.Road construction has the characteristics of high cost,large investment,many points,long line,high quality requirement and complex outdoor working environment.In order to assist the road construction department to construct scientifically and efficiently,this paper develops a road construction management system based on BIM+GIS in combination with the characteristics and management requirements of road construction.This system takes Visual Studio as development environment,C# as development language,SuperMap Object.NET as GIS component to develop the system,and SQL Server as data management.The road BIM model is created by BIM software and integrated into the GIS platform.This research involves 41 500 topographic data,371 three-dimensional spatial data including pavement and roadbed,450 construction list data,450 construction progress maintenance data,1 350 construction progress report data,450 construction cost data,50 pavement construction quality monitoring data and other related construction information data.The system mainly developed 12 functional modules,including GIS data management module,BIM data management module,two-dimensional synchronous display module,model information viewing module,view module,terrain analysis module,measurement module,construction data management module,construction list management module,construction progress management module,construction cost management module,construction quality management module,a total of 39.A functional interface.In this study,the effectiveness of the system is validated by the road construction of a section of the national highway G107 from Handan border to the south of Matou.Combined with two-dimensional GIS route and three-dimensional road scene,the construction data are sorted out and filed according to category,the quantities of each section are analyzed,the construction progress is monitored and analyzed dynamically,and the construction cost is analyzed dynamically.According to the evaluation model of pavement construction quality,the pavement construction quality is evaluated to realize the visual management of road construction.
