Navigation and quality of construction processes
Mohlenbrink, Wolfgang & Volker Schwieger
Engineering geodesy and geodetic measurement techniques deliver important information within construction processes. This is valid for all phases of the process: the planning phase, the construction phase itself as well as the monitoring after finalisation of the construction work. The aim is the delivery of information in realtime to navigate construction processes with the help of the latest available geometric data. The basis for the solution will be a integrative description of the process, the data and the quality. Geodesists and civil engineers often have their own, sometimes non-compatible, way to describe the quality of geometric data. Frequently they are restricted to the use of the quality criteria accuracy, although other criteria like correctness or availability are of the same importance. The authors will show the demand for a quality model that includes inherent quality criteria and parameters through the whole construction process. The different topics regarding quality demands, quality model, quality assurance, realtime documentation of the construction process and navigation of the construction process are demonstrated for the setting out of high-speed tracks. The positive effects caused by the quality assurance actions will be demonstrated.
