OpenTunnel Designer
Transportation design and civil infrastructure software
OpenTunnel Designer manages parametric tunnel geometry, component modeling, reinforcement and deliverables while connecting civil alignment and geotechnical analysis workflows. It is a design-authoring environment rather than the ground-response solver itself.

Senior-engineer perspective
Carry accepted geometry and design intent through the delivery workflow.
OpenTunnel Designer manages parametric tunnel geometry, component modeling, reinforcement and deliverables while connecting civil alignment and geotechnical analysis workflows. It is a design-authoring environment rather than the ground-response solver itself.
Maintain geometry, context and engineering decisions in a model-driven civil workflow.
Evaluate alternatives earlier and carry accepted design intent into detailed delivery.
Apply parametric tunnel modeling for multiple tunnel types where that capability directly supports the project decision.
Technical scope
Civil modelling functions that protect design continuity.
Only capabilities supported by the reviewed source-controlled product record are shown here. CTtec adds engineering context without reproducing Bentley marketing copy.
Parametric tunnel modeling for multiple tunnel types
Automated PLAXIS analytical-model creation
Drawings, reports and reinforced-concrete detailing
Engineering workflow
Survey and context in. Coordinated civil deliverables out.
The sequence is assembled from the product's reviewed capability/application data and CTtec discipline vocabulary. It is a project-use model, not a claim that every project follows an identical process.
Engineering inputs
Survey, terrain, geometry, design criteria, utilities and project context

Product selection guidance
Use the tool that matches the project stage—from option development to detailed production.
Selection guidance is CTtec engineering editorial based on the reviewed product scope. It is intended to support tool choice, not replace project-specific engineering judgement.
Use OpenTunnel Designer for tunnel BIM and design documentation; use PLAXIS for soil-structure interaction and OpenRoads/OpenRail for the controlling corridor alignment.
- Confirm the current Bentley system requirements and licensing terms before deployment.
- Validate project data standards, coordinate systems, units, and exchange formats during implementation planning.
