The compendium is written by the accompaniment of the realisation of a project in the 23rd district of Vienna, which is a manual for architects on commencing their initial post-education project and the real-economic consequences addressed by that. Based on the 9 service phases of the HIA 2010, the general planner responsibility is described step-by-step, attached with important background information and material with an emphasis on risk management and risk minimization. All related bureaucratic and legal steps are explained. Besides the main project, several other practical examples are given and show the differences and risks in every single phase. Gaps between educational theory and real-economical practice are analysed and solved. Furthermore basic legal rules and obstacles are shown, design criteria are calculated, and the process of permissions and construction works is analysed. The thesis is completed by examples of contracts (HOAI, ÖNORM B 2110, etc.), floor and section plans, construction time plans, and several checklists.
