When an entire site is to be developed, the question always arises: How much detail does which building need? The answer not only determines the quality of the planning basis - but also the costs and efficiency of the entire project.
The problem of undifferentiated surveying
Many site developments start with a standard survey - all buildings with the same level of detail, regardless of their relevance to the development. The result: high costs for buildings that are demolished and too little detail for the buildings that really count. A study by the Swiss Association of Engineers and Architects shows that up to 30% of the surveying work involved in site developments is spent on objects that no longer play a role in the subsequent planning process.
Graduated modeling depth as a solution
VDE used a differentiated modeling concept for the core foundation site in Rapperswil: Main buildings with high development relevance were fully modeled inside and out. A demolition object was only recorded as a volume - for spatial classification within the overall site. Outbuildings were given simplified exterior models with windows, doors and roof structures for a coherent overall picture. The result: an area-wide coordinated model that is precise exactly where the planning needs it.
What this means for clients
Site developers, investors and foundations receive a cost-optimized solution with this approach, which nevertheless provides all the bases for decision-making. Feasibility studies, utilization concepts and comparisons of variants can be carried out on a common, reliable database. And the model remains expandable: as soon as a building comes into focus, the level of detail can be increased at any time.
Conclusion
Smart modeling does not mean less quality - it means targeted quality. The right level of detail in the right place is the result of experience and project understanding.
