摘要：With the advances in the field of information technologies, construction industry has started taking advantages some of these developments. GIS is the tool used to manage construction projects and can improve the construction planning and design efficiency by integrating locational and thematic information in a single environment. This paper discusses the potentials of using 3D-GIS spatial operator tools, e.g. 3D intersection & 3D difference in managing construction project activities. It applies the polygonal edge- clipping method for simple object intersection in Geo-DBMS environment. This method extends the problem of point-in-3D polygon in solving spatial operation that has been commonly used in GIS. It has been recognized that 3D union and 3D intersections are among important spatial operators in 3D-GIS. The developed analytical operations have been tested using UTM 3D building model. SQL query has been coded into the program to update automatically building information model (BIM) semantics into Geo-DBMS. Finally, the paper provides outlook to the proposed work towards the development of advanced analytical solutions in 3D-GIS domain
