Abstract:
The diploma thesis deals with optimisation in the building industry. First, theoretical basics are clarified with reference to the topic of optimisation. This is followed by an investigation of the need for optimisation in domestic construction projects. The investigation is based on selected criteria. These include economic and planning aspects. In addition, it is examined whether the sustainability of construction projects can be the basis for optimisation. Based on the results of the necessity studies, selected optimisation approaches are presented. Among other things, approaches based on the use of Building Information Modelling are presented. In addition, methods are presented that are intended to optimise the calculation of construction projects. As a result of the overview of the optimisation approaches, a comparative analysis is presented. Following on from this, selected optimisation approaches are examined on the basis of further criteria. The integration of the approaches into the planning process is analysed and the respective planning and calculation basis is explained. In addition, the extent to which the success of an optimisation can be proven is examined. The presentation of the approaches is followed by an analysis of the HOAI, AHO and DIN 276 with reference to the integrability of optimisation approaches. As a result, the corresponding need for adaptation of the regulations is worked out. Finally, a recommendation for the application of optimisation approaches can be given.
