Abstract:	The technical development of the new Austrian tunnelling method has made decisive progress in recent decades, although mostly unnoticed by the general public. There is little reason for worry regarding possible or necessary technical developments in the future. What is dangerous for the construction method is the increasing concentration of the people involved in the project on purely contractual discussions, while the necessary collaboration on technical development is ever less important, as is the role of the technicians and engineers. In order to counter this and ensure the future of this method of construction, the essential and unaltered basic principles of the NATM and the role of the engineers must retain their former importance. There are a few positive examples, which point to the development potential and the constraints, which will be necessary in the future. Die technische Entwicklung der Neuen Österreichischen Tunnelbaumethode hat in den letzten Jahrzehnten weitgehend unbemerkt von der Öffentlichkeit entscheidende Fortschritte gemacht. Es gibt wenig Anlass zur Sorge hinsichtlich der möglichen und notwendigen künftigen technischen Entwicklungen. Für die Baumethode gefährlich ist die zunehmende Konzentration der Projektbeteiligten auf rein vertragliche Diskussionen, die notwendige gemeinsame technische Abwicklung gerät ebenso wie die Rolle des Technikers immer mehr in den Hintergrund. Um dem entgegen zu wirken und die Zukunft dieser Baumethode abzusichern, müssen die wesentlichen, unverändert gültigen Grundsätze der NÖT und die Rolle des Technikers wieder gemeinsam in den Vordergrund gestellt werden. Es gibt positive Beispiele, die das Entwicklungspotenzial und die künftig notwendigen Randbedingungen aufzeigen.
