Bridge Design for the AI Era
Year 2026
In your right hand, you're experiencing AI like science fiction movies promised. Voice assistants, autonomous vehicles, generative AI creating art and code.
Then you come to work and design bridges with tools developed in the 1990s?
You don't have to.
-
Parametric Modelling
Bring alignment from roadway engineers with LandXML. Build your bridge model parametrically - your 3D model, FEM, and 2D drawings all generate from the same set of bridge parameters.
-
Your Expertise + AI
Use your engineering expertise or leverage AI to configure bridge parameters. Either way, the parametric model updates instantly.
-
Run FEA in Your Browser
Deterministically capture structural behavior. We built an advanced FEA engine from scratch in JavaScript - everything your 20-year-old desktop FEA software does, now running in your browser. No installation, no plugins.
-
Verify per AASHTO LRFD
Deterministically validate your designs against the latest 10th Edition specifications. Every check is transparent and traceable.
-
Optimize with AI
AI explores thousands of design variations using neural networks and genetic algorithms. Every AI-suggested solution is deterministically verified by the FEA engine and spec checks - no black boxes, just optimized designs you can trust.
-
Export Deliverables
- Calculation Package: Export to PDF
- 3D Model: Export to DGN with pay item attributes attached
- Open Data Standard: Export to IFC - OpenBrIM powered USA's first open standard-based bridge delivery
- 2D Drawings: Generate parametrically and export to DGN using your agency's seed files
Beyond Delivery: Parametric Asset Management
Your OpenBrIM model isn't just a deliverable - it's a living asset that evolves with your bridge.
During Construction
Update as-built parameters in real time. Field conditions change - your model stays current. Every modification instantly recalculates FEA results, load ratings, and code compliance.
After Each Inspection
Enter deterioration parameters through a simple spreadsheet interface. OpenBrIM instantly recalculates your bridge's load rating using influence surface-based live load analysis - no re-modeling required.
Permit Routing
Input permit truck configurations and instantly calculate Rating Factors with full code compliance checks. Know exactly which bridges can safely accommodate each load based on current condition.
Portfolio-Wide GIS View
See all your bridge assets in a unified map view with real-time condition data. Monitor exact locations, current ratings, and inspection status across your entire infrastructure network.
Complete Revision History
Track every change to your bridge over time. See how deterioration parameters and rating factors evolve. Full audit trail for compliance and decision-making.
Zero Installation
All of this runs in your web browser. No software to install, no licenses to manage. Access and update your bridge models from anywhere, on any device.
From 2D Plans to Accurate Quantity Takeoffs
Turn existing 2D drawings into 3D models and extract precise quantities for competitive bidding.
Import 2D Drawings
Start with what you have - 2D plan sheets, cross-sections, and details. OpenBrIM reads your existing drawings and helps you build a parametric 3D model in a fraction of the time.
Generate 3D Model
Transform 2D information into a full 3D parametric model. Every component - girders, deck, barriers, piles - is modeled with accurate geometry and material properties.
Extract Quantities
Get precise quantities for every pay item directly from the 3D model. Concrete volumes, reinforcing steel weights, structural steel tonnage - all calculated automatically with full traceability.
Pay Item Mapping
Map model components to your agency's pay items. Export quantity reports organized by bid item codes, ready for your estimating software.
What-If Scenarios
Explore alternative construction methods quickly. Change parameters and instantly see how quantities and costs change - helping you find the most competitive approach.
Win More Bids
Accurate takeoffs mean tighter bids without leaving money on the table. Know exactly what you're bidding on and price it right.
AI-Powered Asset Counting
Point your camera at the job site or warehouse. Our AI instantly counts materials - no manual tallying required.
Snap. Count. Done.
Take a photo of stacked materials at your job site or warehouse. OpenBrIM Count uses computer vision to instantly identify and count individual items - saving hours of manual inventory work.
Custom-Trained for Construction Materials
We specialize in training vision models for construction industry materials. Whether it's a staging yard, warehouse floor, or delivery truck - the AI learns to recognize exactly what you need to count.
Inventory Verification
Verify material deliveries match purchase orders. Catch discrepancies before signing off.
Warehouse Management
Track stock levels with photo-based counts. Know exactly what's on hand without manual audits.
Pay Application Support
Document materials on site for progress payments. Photo-verified counts for billing accuracy.
