Areas of Expertise

Infrastructure and Residential Engineering

We have been engaged in hydraulic engineering since 1986. Thanks to our expertise and experience of several decades, even the most complex problems can be solved.

Since we have expanded our field of activity in the area of traffic route construction in terms of personnel as well as in terms of software, we are able to offer the highest level of competence. In recent years, our team has specialized in the rehabilitation of water supply systems and wastewater treatment plants, which enables us to provide extensive knowledge for our customers in this area too. This expertise is underpinned by the training as a certified sewer rehabilitation consultant of qualified engineer Mr. Obernosterer, as well as by the training as a certified water master of qualified engineer Mr. Scherzer. Our main focus lies on ensuring continuous support from the client’s initial project idea to the realization and implementation of the project.

In addition to his studies in Industrial Engineering at the Graz University of Technology, Mr. Obernosterer took the civil engineer exam and completed an apprenticeship as a sewer rehabilitation consultant. He has been in his responsible position at OKZT for almost 10 years now.
