About us

Planning for what's ahead.

Technical drawings are our core business. From Dreieich, we support engineering consultancies and construction companies in building, civil and industrial construction – combining decades of experience with modern, BIM-ready 3D planning.

Our development.

  1. Our beginnings in Dreieich

    Sebastian Zehentner Technische Zeichnungen GmbH is founded.

  2. Moving forward together

    Zehentner + Ingenieure Technische Zeichnungen GmbH continues this tradition as the successor to the previous company and takes over all employees.

  3. Today

    Experience. Developed digitally.

    From Dreieich, we combine technical drawings with 3D models and BIM.

Digital planning. Personal collaboration.

We produce structural, formwork and reinforcement drawings, as well as steelwork overviews, excavation support, bored-pile and precast element drawings. We use ALLPLAN for drawings and 3D models; BIM supports coordination within the project team.

One contact. Reviewed results.

The responsible project manager oversees, reviews and coordinates your detailing work and remains your direct contact throughout the project – for clear communication, consistent drawing quality, reliable schedules and economical solutions.

Whether for individual projects or temporary capacity shortages: our experienced detailers support you on a project basis – from the first coordination meeting through to the final, coordinated set of drawings, in close partnership.
