Online-monitoring of the subway station Erdberg Vienna
Abstract
In modern construction and planning industry, especially renovations (restructuring measures) of old objects, objects in operation etc. the safety aspect becomes more important. A potential source for hazards and damage during renovation respectively conversion can be caused by uncontrolled deformation of directly or indirectly affected object parts. Therefore it is obvious that deformation behavior of these object parts should be investigated as precisely as possible before the rebuild and monitored at best during construction works and to determine its magnitude. Thus in this context about a technique which is not brand new but has not been used all too often – the online geomonitoring- is spoken, where online observations of such deformations using geodetic methods are possible. Under suitable measuring arrangement nowadays even minor changes to building or plant components can be automatically detected. The Online Monitoring System used by Vermessung ANGST ZT GmbH (in combination with the software GOCA) offers on the one hand an overview of the observed object's condition of change that is retrievable via internet at any time and on the other hand, in case of exceeding the tolerance values, an automatic alert system with optical-acoustical warning for all present on the spot and alerting of those responsible by SMS or e-mail. By online monitoring and with responsible chosen tolerance value an exposure can be recognized in a timely manner. The following is a report on the online- and geomonitoring and alerting in the completed project of the transport hub A4/A23 (“Node Prater”).
