At the occasion of the 10th anniversary after the Berlin Main Station was officially opened to train traffic, a view back on eight years of monitoring was given. For the period of the construction with different load cases, the monitoring system was required by the Railway Authorities (Eisenbahnbundesam, EBA) to survey differential vertical displacements between neighbouring supports of the glas roof and the partially prestressed middle bridges. 128 sensors were installed.The data was published in the Internet with access restricted to the BAM scientists and the owner of the station, the German Railways DB AG.

N2 - Civil engineers, who are involved in nondestructive testing have to solve an essential task: the transfer of the results of NDT-research into practice. NDT in civil Engineering is a quite new discipline. The results must meet the needs of the infrastructure owners to convince them about the usefulness of NDT. The issue of reliability of the NDT-data was discussed.

Der Vortrag stellt den Stand der Möglichkeiten zur Quantifizierung von Ergebnissen der zerstörungsfreien Prüfung dar. N2 - The reliability of data, obtained from nondestructive testing depends on many different factors as e.g. the equipment, the human factor, the influence of material properties, geometrical accessibility of the given detail, the structure of the detail, but also from data acquisition, processing and interpretation. The presentation introduces to current possibilities for the quantification of measurement results received during nondestructive testing.
