In this paper we want to emphasize the current challenge in integration of BIM, GIS and CAD. In BIM can be identified and managed the existing relationship between architectural, structure layout and mechanical, electrical and hydraulic services. GIS is managing locations, identifying trends, patterns and 2D or 3D models. Integrating of GIS and BIM (originally developed for different purposes) will have an important impact on solving problems in the civil, building and infrastructure sectors. In our study were ana...

When documenting of existing bridges, object geometry knowledge is the highest importance. Complex construction documentation usually has limited spatial representation of the object, based on a limited number of basic forms of modeling, represented by edges, corners, planes and volume elements of the real object, and depending on the purpose, the model results must match within a certain accuracy with real object. Rehabilitation of bridges also involves the realization of detailed plans in situations where they n...
