Gradon
Drafts full civil, structural, and MEP deliverables inside Civil 3D, Revit, ETABS.
Gradon works like an engineer you message directly: give it a brief and it drafts the full deliverable — a 62-sheet civil CD set, a 191-page structural calc package, a Revit model with tagged floor plans — inside the software your firm already uses. It's not self-serve: the team onboards in person, builds a 'Firm Brain' from your past projects and standards, and spends at least a week in your office tuning each workflow. Firms report 75% less time per project and 2x revenue per engineer, with every deliverable reviewed by your team before it goes out.
What holds up
- +Outputs match your firm's own standards because it trains on your actual past projects first.
- +Works directly in Civil 3D, Revit, ETABS, and Bluebeam — no exporting to a separate AI tool.
- +Onboarding team sets up your workflows in person, then stays on in a shared Slack channel.
Mind the limits
- −Output still needs a licensed engineer's sign-off — it drafts the work, not the stamp.
- −Not self-serve — onboarding means a team in your office for at least a week, with no price listed.
