What is OpenTunnel Designer?
OpenTunnel Designer is the first and only purpose-built software for tunnel modeling and design. Get the right tools for the job and say goodbye to unnecessary rework and time delays with all team members now working in one intuitive application.
Automated Tunnel Modeling
Simply create tunnel-specific objects and information in one application that all team members can intuitively use. Eliminate coding, scripting, and workarounds.
Multi-Discipline Collaboration
Easily share and consume a variety of file formats across project stakeholders. Prevent errors, rework, and costly delays with always up-to-date data.
All-In-One Workflow With PLAXIS
Conveniently import existing OpenTunnel models into PLAXIS and generate the analytical model with a click of a button. Replace recreating models with extra time to analyze and optimize projects.
OpenTunnel Designer is the first and only purpose-built software for tunnel modeling and design. It introduces a single common data environment
so all project stakeholders can reliably consume and share up-to-date data. Easily exchange information with Leapfrog, PLAXIS®, OpenRoads™, OpenRail™, OpenBridge®, and ProStructures to identify errors early and create alternatives for optimum design, safety, and performance.
Rich In Engineering Content
OpenTunnel Designer has all the right tools for the job. produces intelligent, parametric models that are rich in engineering content properties for various tunnel components. Model the full excavation shape, excavation tracks, tunnel lining and tunnel reinforcement. Model, analyze and design as a true 3D solution, as well as perform clash detection with other structures, objects, and utilities to eliminate problems before they occur.
Design Simplification
OpenTunnel Designer reuses data from various stakeholders, thus maintaining relevant and up-to-date geometry within a single model. Save valuable
design time as your model updates automatically to any change made in the tunnel template or alignment geometry. Comprehensive and automated design tools remove the need for scripting specialists and multiple applications. Matched with dynamic change. management, it mitigates rework and reduces time delays with all team members now working in one intuitive application.
Efficiency Based Design
OpenTunnel Designer allows direct referencing of DGN models with road/rail/bridge information created with OpenRoads, OpenRail and OpenBridge applications. If reference data changes, the parametric and rule-based tunnel model automatically responds to those changes. Its seamless interoperability with ProStructures can be used for reinforcement detailing, maximizing collaboration between different teams and disciplines throughout the design process.
Production Improvements
Modeling in a 3D environment helps rapidly verify tunnel geometry. The tunnel is seen in plan, elevation, and cross-section views. A variety of deliverables can be generated using OpenTunnel Designer. It also facilitates the evaluation of multiple tunnel alternatives, and costs reports, and well-organized analysis and design reports. Create annotated plans, elevations, and sections using MicroStation’s Dynamic View feature and OpenRoads Named boundaries. Easily publish project information with a variety of report generation options. Reports can be printed to PDF, saved as HTML files, or exported to spreadsheets. Generate i-models to convey rich project information to stakeholders.

Consume soil strata and linear infrastructure data with ease. Reference road and rail corridors, and bridge structures in your OpenTunnel Designer model and quickly import soil meshes with IFC versions 4.0 and 4.3.
- Model the full excavation shape, excavation tracks, and the tunnel lining and reinforcement for conventional and mechanized tunnels.
- Model interior objects that are to be extruded along the tunnel length or placed as cells along a specified path, such as sidewalks, ducts, cable trays and more.
- Save valuable design time as edits automatically update in visualizations, plan production, and quantities reports.
- Model and detail the rebar reinforcement for the tunnel lining. Reference your OpenTunnel lining model in ProConcrete and see changes automatically reflected in the reinforcement data and deliverables based on the tunnel lining geometry changes.
Maximize productivity and save time by creating multiple analytical models in minutes not days. Simply specify stations for the cross section as the basis of your 2D analytical model or send entire tunnels from your 3D BIM model to PLAXIS with the push of a button, no coding required.
Streamline your plan production process. Plan, profiles, and cross-section drawings can easily be created using OpenTunnel Designer’s powerful drawing production tools. Keep your projects on track with tunnel specific reports based on the latest changes for up-to-date accurate costing and quantities.
