CAD—GIS BIM Integration—Case Study of Banja Luka City Center

Abstract

This article provides a sneak peak of ongoing technology integration efforts targeting fields of computer aided design and drafting (CAD), geographic information systems (GIS) and building information modeling (BIM). CAD enables ad hoc drawing and sketching spatial plans. GIS adds geospatial component to it, making your drawings and associated objects spatially aware. BIM goes one step further and establishes relationships between the drawing objects, making them more “intelligent” and suitable for future processing and analyses. With each step data classification requirements increase dramatically, so is the time required to complete one. Most users focus merely on just a single of aforementioned components, be it CAD, GIS or BIM—as overall complexity of “tying it all up” requires considerable amount of time and effort, while most often being out of project’s scope and/or deliverables. This highly affects general data reusability on the output. Ongoing project’s aims may be reached, but its overall value will be higher if you made results more reusable.
