When everything just comes together...

pbo was founded in 1993 by Prof. Dr.-Ing. Thomas Pretz, Dipl.-Ing. Thomas Bergedieck and Dipl.-Ing. Klaus Jörg Onasch.


As engineering consultants, pbo performs its services free of supply, performance or commercial interests from trade and industry.

pbo provides practical solutions in issues of waste management and technology, which go well beyond pure project management activities.

We are in constant contact with what is happening on the ground and you will be sure to benefit from our applied practical experience. Whether civil engineering, hydraulic engineering, industrial or commercial construction - besides structural engineering, we can also apply our detailed know-how regarding mechanical process engineering to drafting, implementing and integrating complex plants as part of your construction project.

We will supervise and support you from the initial idea through to the project planning and implementation and the organisation of your projects.
