Describe it or draw it.
TorenOne designs it.
TorenOne is an AI structural design agent. Describe a steel portal frame or upload a drawing — it drafts the design, then runs the full SANS check on a deterministic engineering kernel (members, connections, baseplates and footings), not an AI guess. Review, confirm, and download a stamp-ready calc package in minutes.
Every number cited to a SANS clause · the registered engineer stays the authority.
Computed against the standards your Pr.Eng already trusts

What you get
Built for real engineering work
Not a chatbot that sounds confident — a design agent that does the work and shows its working.
Brief or drawing, in
Describe your frame in a sentence, or upload a drawing or plan. The agent extracts a typed spec — reading only what you stated or labelled, never guessing an engineering number.
Deterministic SANS kernel
Loads, analysis and every code check are computed by a tested, version-pinned engine. Same inputs, same answer — every single time.
The whole frame
Members, eaves & apex moment connections, column baseplates and pad footings — sized and checked end-to-end, not just the rafters.
Stamp-ready calc package
A clause-referenced PDF with diagrams, show-your-working and an audit fingerprint. Your engineer reviews, verifies and stamps.
Check mode
Already chose your sections? Verify them against every SANS clause in seconds — the lower-liability path where you stay the author.
Built for firms
Multi-tenant with strict per-firm isolation, owner-invited teams and a full run history. Your projects and reports stay yours.
How it works
From a brief or a drawing to a stamp-ready package
Three steps. Minutes, not days.
Describe or upload
Describe the frame in plain English, or upload a drawing or plan. The agent turns it into a typed, reviewable specification — reading only what you stated or labelled, never inventing a value.
Review & confirm
Check the inputs on an editable form with a live elevation sketch. You stay the authoritative pilot — nothing computes until you confirm.
Get the calc package
The deterministic kernel runs the full SANS design — loads, analysis, members, connections, foundations — and hands you a stamp-ready PDF.
Why it’s different
You don’t need another chatbot.
You need calcs you can stamp.
Portal frames have been designed the same way for twenty years — by hand, in spreadsheets and desktop software built in the 2000s. Slow, manual, impossible to scale. And generic AI can’t replace it: it guesses, and you can’t stamp a guess.
TorenOne is built AI-native from the ground up, not a chatbot bolted onto a legacy interface. Your brief — or your drawing — goes to a deterministic, version-pinned structural engine, validated clause-by-clause against the SANS standards. Reproducible. Cited. Stamp-ready. It’s the workflow the incumbents can’t retrofit onto twenty-year-old software, and the one your firm can finally trust. Accuracy is the product.
Stop hand-cranking portal frames.
Built for South African structural engineering firms designing single-bay steel portal frames. Lead with Check mode, scale with full Design mode.
