In this master thesis the potential of BIM is analyzed on a case study of the actual multi-dwelling building project. In the theoretical part, the thesis addresses the advantages and general concepts of BIM. Then a detailed overview of the advantages of quantity take-off, interoperability, and project execution are presented. Accurate quantities determine the budget and the schedule. Hence, they are essential for project optimization in terms of budget and schedule. Therefore, in the second part, BIM is used on a reference project to demonstrate the possibilities of the BIM approach.
The author has performed an action research and participated as a member of the general contractor team for the whole duration of the construction on the site. This approach allowed gaining valuable project information that covered both the detailed production of the documentation as well as information on the problems and difficulties of the project documentation which was developed without BIM. After completion, we selected a BIM tool and developed a BIM model.
The BIM model was used for quantity take-off and the 4D model where the interoperability based on the IFC was deployed. The results were used for the analysis and comparison of actual and BIM-based quantities and sequencing of construction works. A 4D simulation was used to compare the planned and actual execution of the construction works. Based on the comparison of actual sequencing, we identified opportunities for the improvements using the BIM approach.
