      Increase your productivity with OpenTunnel Designer

      OpenTunnel Designer increases productivity up to 50% and provides you with purpose-built tools for the job at hand. The software helps eliminate unnecessary rework and delays by allowing project members to work in one easy-to-use application. Easily exchange information with other Bentley applications such as Leapfrog, PLAXIS, OpenRoads, OpenRail, OpenBridge and ProStructures, so you can have a unified workflow for analysis, design, and performance.

      Data integration

      Improve your decisions by being able to combine, organize, and manage geotechnical and existing conditions data quickly and accurately. With OpenTunnel Designer you can work with soil strata and linear infrastructure data, as well as, reference road and rail corridors, and bridge structures.

      Model, simulate, and detail

      Model the full excavation shape, excavation tracks, and the tunnel lining and reinforcement. Native modeling tools help you save design time, by making automatic updates as a result of any change made to the tunnel template or alignment geometry. Model and detail the rebar reinforcement and reference your OpenTunnel tunnel lining model in ProConcrete.

      Produce drawings and reports

      Streamline how you create plan, profiles, and cross-section drawings with drawing production tools. Reports help keep your project on track with up-to-date costing and quantities.
