Title:
Abstract:	The consistent application of the observation method on shield tunnel drives can make a considerable contribution to preventative dispute avoidance and conflict reduction when issues occur. The observation method should include not only the monitoring and analysis of mechanical process data such as machine data, control parameters and data from the geotechnical instrumentation but also process control as the tunnel advances, which is documented in the following quality assurance documents: explanatory report, machine concept, incident analysis, specification, tunnelling machine handbook and the tunnelling plan before tunnelling and report after completion. This should be interpreted as a unit and is defined as the holistic observation method. Eine konsequente Umsetzung der Beobachtungsmethode kann bei Schildvortrieben einen wesentlichen Beitrag zur präventiven Streitvermeidung und Konfliktreduzierung bei Störsituationen leisten. Dabei soll die Beobachtungsmethode nicht nur die Überwachung und Analyse der maschinentechnischen Prozessdaten wie Maschinendaten, Steuerungsparameter und Daten aus dem geotechnischen Messprogramm einschließen, sondern auch die Kontrolle des vortriebsbedingten Prozessablaufs beinhalten, der durch die Qualitätssicherungselemente Erläuterungsbericht, Maschinenkonzept, Störfallanalyse, Pflichtenheft, Schildhandbuch und Vortriebsvor- und -nachschau dokumentiert ist. Dies ist als Einheit zu interpretieren und wird als ganzheitliche Beobachtungsmethode definiert.
