In large-scale projects, the different participants in the construction process often use the same construction sites. The sites are used, for example, as areas for crane installation or construction site equipment. In addition, the terrain of the construction site changes during the process, e.g. due to new buildings. These changes make it difficult to imagine the condition of areas at certain construction phases and thus make the coordination of the construction process more complicated. In the classical work preparation method, coordination is by means of construction plans and construction schedules. This bachelor thesis examines whether coordination improves by applying a model-based working method. The results of this examination serve as a basis for a recommendation for future projects. In this context the model-based working method is applied to a case study in civil engineering. For this purpose, a construction phase is prepared as a 4D model and linked to a schedule. With the help of an expert interview the determination of crane areas according to the classical working method is shown as an example. Finally the model-based method is contrasted with the classical working method. The comparison is based on selected criteria. These criteria also serve for answering research questions as to the level of detail, early models and increased flexibility. The analysis of the comparison results reveals that, referring to the case study, the model-based working method includes a quality-increasing potential and a larger range of functions in the processing of planning tasks, due to its methodological approach. For this reason, it is recommended to use the modelbased working method for large-scale projects with a degree of complexity, comparable to the case study.
