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.

OpenTunnel Designer data

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 with OpenTunnel

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.

Tunnel Drawing and Reports

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.

Testimonial_Quote_Marks
“With OpenTunnel, the design can be made directly by the drafter, and the engineer can concentrate on the calculations in PLAXIS and the design of the work. It is a way to save time and optimize everyones work.”
Testimonial_Quote_Marks
“Compared to other BIM tools and applications in the as-built generation and maintenance interventions of a standard application, we can estimate 50% time saving to build the same model. In the case of long and complex tunnels, time-saving could be even larger.”
Testimonial_Quote_Marks
“OpenTunnel is a powerful tool for designing tunnels and all associated structures. The automatic implementation of the reinforcement is also an indispensable tool that we use very regularly, which allows to save a lot of time and to test several solutions.”

Frequently Asked Questions

What is OpenTunnel Designer?

OpenTunnel Designer is tunnel software for analysis and design of tunnels. It is the first software of its kind that works within a single common data environment, so all stakeholders can consume and share the most up-to-date information.

How much does OpenTunnel Designer cost?

A practitioner license of OpenTunnel Designer costs $5,661 USD. Prices vary per region. While there are various types of licensing available, a common choice is the 12-month practitioner license offered through Virtuosity, Bentley’s eCommerce store. When you purchase through Virtuosity, you get a Virtuoso Subscription. This means you get the software and “Keys” (tokens) to redeem for customizable training, mentoring, and consulting services.
