The article presents an automated system for geodetic control in building of bridge superstructure constructions using the cantilever construction method. The system includes two modules: an observation module consisting of a robotic total station and a portable laptop-tablet with special software and an assembly module connected via a radio interface. During construction, precise geodetic measurements are done to control the spatial status of the cantilever facility and the constructed bridge segments. The correction data are being registered into the total station and then transmitted to the assembly module. This procedure is repeated until the completion of the bridge construction. The author emphasizes the importance of precise measurements and proposes the development of a system with high-precision geodetic tools and means of communication thus providing fast and reliable data preparation for spatial orientation and automated preparation of executive documentation.
