The pumping station at the Schwanenstadt sewage treatment plant, which has been in operation for over 50 years, required extensive renovation work. Due to the age of the plant, there were no current as-built plans and the original planning deviated from the actual execution. The following steps and technologies were used to ensure an efficient and precise refurbishment:

Project scope

Scan of the system
The pumping station was precisely scanned both from the inside and outside and recorded in the correct position. This digital image of the existing structures formed the basis for further planning.

Modeling and plan derivation

The recorded scan data was converted into a detailed 3D model. Based on this model, current plans could be derived, which formed the basis for the renovation measures.

BIM phase modeling

The various renovation phases were visualized using Building Information Modeling (BIM). This enabled the client to track the planned steps, make comments and make adjustments if necessary. This procedure was based on the 4D principle, which integrates time as a dimension and thus enables dynamic planning and control of the construction processes.

Advantages and objectives

Precise as-built survey
The use of modern scanning technologies enabled the actual building fabric to be digitally recorded, which was particularly important as no current plans were available.

Efficient planning
The 3D model created made it possible to identify discrepancies between the original planning and the actual execution and to integrate them into the renovation planning.

Dynamic renovation control
Thanks to the BIM-based 4D visualization, all renovation steps could be planned and monitored in detail, allowing the project to be implemented smoothly.

This comprehensive approach means that the Schwanenstadt pumping station is not only being renovated, but also future-proofed to meet the requirements of the coming years.
