Title:
Abstract:	The construction of subsurface underground structures poses a special challenge for the involved project team. The goal of geological documentation is to record the conditions as precisely as possible and provide support to the entire team based on this information. To this end, the situation is recorded during the advance, sketches are drawn, digital photos are taken and measurements are made. It has now become standard practice to store and evaluate the data obtained digitally. For this purpose powerful computerized information systems have been developed to store and evaluate large amounts of data. Geological observations in underground construction are almost exclusively spatial information and are recorded in three dimensions. In addition to the types of rocks encountered, the positional relationships of the geological bodies to each other and the discontinuity system of the rock mass have a great influence on the stability of the cavity. Future developments will be concerned with the integration of the geological data into BIM systems. Compared to present GIS techniques this will enable a more effcient aggregation with other tunnel construction data. Mobile applications will make it possible to record observations directly in digital form, thus avoiding redundancies. Ziel der baugeologischen Dokumentation ist es, die Verhältnisse vor Ort genau zu erfassen und auf der Basis dieser Informationen den Bauherrn, die ausführende Firma und das Team hinsichtlich möglicher Gefahrenpotenziale bestmöglich zu beraten. Zu diesem Zweck werden die Situation beim Vortrieb aufgenommen, Skizzen angefertigt, Digitalfotos erstellt und Messungen durchgeführt. Die Daten digital abzulegen und auszuwerten, ist bereits Standard; leistungsfähige Fachinformationssysteme erlauben es, große Datenmengen in geeigneten Datenbankstrukturen abzulegen und auszuwerten. Bei geologischen Befunden im Hohlraumbau handelt es sich fast ausschließlich um Informationen mit räumlichem Bezug, die dreidimensional zu erfassen sind, weil die Lagebeziehungen der geologischen Körper zueinander und das Trennflächensystem des Gebirges neben den angetroffenen Gesteinsarten Einfluss auf die Stabilität des Hohlraums nehmen. Zukünftige Entwicklungen beziehen sich u. a. auf die Integration der geologischen Daten in BIM-Systeme, um eine leistungsfähigere Zusammenschau mit anderen Datenbeständen zu ermöglichen als dies bereits mittels GIS realisierbar ist. Mobile Anwendungen werden es ermöglichen, Beobachtungen im Vortrieb unmittelbar digital zu erfassen, wodurch Redundanzen vermieden werden können.
