OpenTunnel Designer

OpenTunnel Designer is the industry's only purpose-built, all-in-one application for tunnel design. While competitors force you into a fragmented workflow, stitching together general-purpose tools and then exporting to a separate analysis program, OpenTunnel Designer integrates everything. This eliminates risky data transfers and the need for custom scripting, saving significant time and reducing errors.

Through a seamless, one-click connection, which is a major competitive advantage. Instead of manually exporting geometry and re-creating data, you can send your complete 3D tunnel model, along with soil data and structural properties, directly to PLAXIS. This unmatched integration ensures your analysis is always based on the definitive design model, a level of accuracy and efficiency that is impossible with disconnected, multi-vendor workflows.

No. It is a specialized BIM for tunnels platform. General BIM tools are designed for buildings and require extensive workarounds for complex civil infrastructure. Every tool in OpenTunnel Designer, from its parametric modeling engine to its automated drawing production, is designed specifically for tunnel projects. This results in a much faster, more intuitive workflow that produces a data-rich digital twin ready for construction and operations.

It uses automated, purpose-built tools designed for these specific challenges. While generalist software would require hours of manual modeling and complex workarounds to create intersections between tunnels, OpenTunnel Designer provides automated functions to generate these connections accurately in minutes. This includes advanced tools for tunnel trimming and an integrated rebar modeler for detailed reinforcement.

Through seamless interoperability with the Bentley ecosystem. OpenTunnel Designer can live reference road and rail alignments from OpenRoads Designer and OpenRail Designer. If the alignment changes, the tunnel model is notified to update. This dynamic link eliminates the significant risk and cost of designing a tunnel based on outdated information—a common and costly problem when using disconnected software.

OpenTunnel Designer is used to streamline the entire workflow by integrating 3D modeling, geotechnical and structural analysis, and the generation of deliverables into a single, unified environment, eliminating fragmented workflows and custom scripting.

OpenTunnel Designer is built for the entire multi-discipline tunnel project team. Its primary users are tunnel engineers, geotechnical engineers, and structural engineers responsible for detailed modeling and analysis. Additionally, project managers and BIM managers use it to streamline collaboration, mitigate risk, and ensure compliance with digital delivery mandates.
