Abstract

The presented dissertation deals with claim management for larger construction projects from the point of view of professional clients. It focuses on the holistic consideration and organizational implementation of supplement management, which can be identified as a research gap after systematic literature research. The client's claim management is examined with the dissertation with regard to the actions to be included and the organizational boundary conditions of both the individual project organizations and the higher-level primary organizations of the client. The areas of strategy and organisation, preventive, proactive and reactive claim management are identified as fields of action for claim management, each of which is concretized with further subtasks. The organizational environment of claim management in construction projects is typically shaped by the standard service descriptions of AHO and HOAI. In the environment of the primary organization, the customer departments planning and execution, purchasing, legal and auditing relevant to the construction project can also be identified. In the constructive part of the dissertation, a holistic claim management system on the part of the client is developed in appreciation of the insights gained into the status quo. On the basis of system theory, claim management is described in detail with regard to its functional, hierarchical and structural concept. This explains in particular the coupling of operative claim management in the project organization and strategic claim management within the primary organization. In addition, all tasks of claim management - both at the operational and the strategic level - are described in a process-oriented and contextual manner, distinguishing them from the established standard performance models of AHO and HOAI. Characteristic for the developed claim management system are (1) the hierarchical differentiation into operative and strategic claim management, (2) the assignment of the claim management fields of action to the established project stages, (3) the formulation of a holistic performance profile for the claim management tasks as a supplement to the AHO and HOAI performance profiles and (4) the comprehensive process descriptions of the individual claim management actions. In addition to the development of the claim management system, models for the organizational implementation of integrated claim management are also developed. A key distinction is made between a strategic anchoring of supplementary management in the primary organization and a situational strengthening of supplementary management in the project organization. In the former case, four integration variants are proposed. In the latter case, four common scenarios are described in which it is necessary to strengthen claim management. In each case, recommendations for action are formulated to enable adequate implementation of claim management. The present dissertation thus uses an organisational-systemic approach to contribute to the improvement of the client's claim management and finally to secure the client's project objectives.
