STUDY ON INTEGRATING AND MANAGING BIM FOR CIVIL AND HYDRAULIC ENGINEERING BASED ON 3D WEBGIS

In view of the current shortage in the mainstream integration scheme of BIM and GIS,a BIM data integration and management scheme based on 3D WebGIS is proposed.This method mainly uses WebGL as integrated container,transfers data based on the web service interface,and combines the key technologies to realize the hierarchical integration of IFC model data in GIS environment.According to the above methods,the framework of BIM and GIS prototype system for civil and hydraulic projects is proposed.And based on the knowledge of web programming and the open source tools,the BIM data is integrated in the GIS environment quickly and efficiently,providing a supportive environment for the lifecycle application of engineering.Then the feasibility and applicability of the prototype system are verified through sample data,which shows that it can be widely applied in the field of civil and hydraulic engineering.
