About us
Zehentner + Ingenieure Technische Zeichnungen GmbH is a design office in Dreieich in the Rhein-Main area that has been active in technical drawings since 1986. The company creates structural framework drawings, formwork plans, reinforcement plans, steel construction summaries, as well as excavation support and borehole pile plans for high-rise, civil, and industrial construction projects. Additionally, precast element plans, 3D modeling, and BIM coordination are offered. The software ALLPLAN (Nemetschek) is used; since 2020, the company has been ALLPLAN BIM certified. Reference projects include Terminal 3 at Frankfurt Airport, the FAIR research facility in Darmstadt, the Omniturm in Frankfurt, as well as the Wannsee Terraces and the Berlin Palace. Customers are engineering offices and construction companies that support the team on a project basis or during capacity peaks—from the initial coordination to the coordinated plan submission.
