Keywords: mechanized-tunneling, contracting, compensation models, ÖNORM B 2203-2, digital datamanagement, project analysis, expert intervies This thesis was written in the framework of the research activities to develop an innovative compensation and contract model for mechanized-tunneling an the basis of digitally recorded excavation and machine data, at the Institute of Interdisciplinary Construction Process Management research area Construction Process and Methods. It should serve as a basically analysis for further research work. This thesis starts with the explanation of the selected national and international contract and compensation models, based on an comprehensive literature search. In order to give the reader a general understanding, the first step is a detailed description of the ÖNORM B 2203-2 which is applied throughout Austria and contains the major procedural and contractual provisions for mechanized-tunneling. Based on the proximity and the socio-cultural similarities, there is a closer explanation of the normative regulations from Germany and Switzerland following. Because of the huge amount of international tunneling projects, this thesis contains further explanations of selected standardized contract models that are globaly used. Most of these models do not contain any explicit regulations for tunneling, which is why the implementation is defined separately for projects with mechanical excavation. The contract and compensation model of the Fédération Internationale des Ingénieurs Conseils (FIDIC), New Engineering Contract (NEC), lump sum and alliancing contracts have been selected by the author. Interviews with experts were conducted for the comparative analysis and the project-specific implementation of the examined contract and compensation models. Based on the experiences of the surveyed employers, contractors, and independend consultants, the corresponding considerations and country-specific or socio-cultural characteristics in the implementation of the individual contract models are worked out. Furthermore, this thesis considers advantages and disadvantages for the construction work and compares the perspectives of the different project participants to create the basis for future innovative contract and compensation models. Global digitization is increasing in every area of our lives. Therefore, the second part of this diploma thesis investigates the potential of digital data management in the field of mechanizedtunneling. On the basis of the conducted expert interviews and the analysis of a specific project, the current significance of a digital data management system on the construction site is being determined. Subsequently, it will be examined which data are recorded digitally by a tunneling machine and which processes have to be passed through in order to be usable for the daily construction site processing. Through an objective consideration and the experience of the experts future uses and development possibilities are shown.
