Projects with figures instead of promises.
We show more than photographs: the values behind them – design discharge, gradient, construction time and the final account. Anyone judging whether we can do a job should be able to do it from the numbers.

What every record contains
- Client
- Who commissioned the work and in what role – municipality, district or operator.
- Technical data
- Design discharge, lengths, gradients, head differences, particulars of the execution.
- Scope
- Which HOAI service phases we actually delivered – not just “designed”.
- Cost
- The final account after completion, gross. Not a flattering estimate.
And the recent years?
The projects documented here come from a time when clients still received paper folders. More recent projects will follow as soon as the clients have released them – with municipal work that is routine, but it takes time.
If you need a reference for a particular task, for a tender for instance: ask for it. We will name a suitable project and the contact person at the client.
