For custom home builders
On your jobs, you are the coordination department.
Nobody hands a custom builder a clash report. You get an architectural set from one firm, a structural set from another, stamped weeks apart, and the job of noticing where they disagree falls to whoever opens both PDFs at the same time. Usually that is you, at night. Sometimes it is the framer, at 7 a.m., with the crew already on the clock.

Why this happens to you and not to them
Commercial catches arch↔structural conflict upstream. Residential discovers it at framing.
Clash detection compares 3D models. Your architect issued PDFs and your engineer issued PDFs. There is no federated model to clash, and building one for a single house has never penciled.
A commercial GC employs people whose entire job is finding these conflicts before the field does. On a custom home, that headcount does not exist. The role still exists — it just landed on you.
There is no coordination review between permit and pour. The sets go straight from the printer to the field, and the first real check either set gets is a framer holding a tape.
This is not a discipline problem and it is not your architect's fault. It is a structural gap in how custom residential is delivered. TrueStruct fills exactly that gap and nothing else.
What it checks
Four checks, every one cited back to a sheet, a grid, and a revision date.
The architectural set says rev 09-15. The structural set says rev 10-20. Five weeks of changes nobody carried across. This is the first check TrueStruct runs and the loudest thing it reports, because it is the single most common cause of a field RFI.
Every opening on the architectural plan should have a structural counterpart at the same location and the same width. When it does not — a 6'-0" slider over a lintel sized for 5'-0" — the framer finds out, on the slab, with the crew standing there.
Chained dimensions on a sheet should add up to the stated overall. When they do not, something moved and the note did not. Compared as extracted text, never pixels, so a real dimensional error cannot be absorbed by a visual fit.
Scheduled openings against scheduled structural members. The disagreements that live in the tables rather than the plan views are the ones that survive every set of eyeballs.
Nothing is ever auto-resolved. Every finding opens with its sources and a confidence score attached and stays open until a person — you, the architect, or the engineer of record — decides who is right. TrueStruct does not direct construction and does not touch anyone's stamp.
Written for the person who has to build it
The RFI drafts itself — in English, Spanish, or French — and lands on WhatsApp.
A finding your crew cannot read is a finding that does not get acted on. Every RFI TrueStruct drafts is produced in all three languages through a controlled construction glossary — lintel becomes dintel, not whatever a general-purpose translator guesses — and goes out over email or WhatsApp with the sheet reference attached. No retyping, no telephone game between the office and the slab.
Rise, run, and headroom against the structural opening — the conflict that surfaces after the framing is already up.
See the stair module →Photograph what is built, get advisory observations against the drawings. Beta — use it to catch things early, not to sign off.
Captures and findings queue locally and flush when signal returns. Built for slabs with no bars.
The part most builders miss
3D mode is a line item, not an expense.
3D mode rebuilds the reconciled house from the same two sets and pins each conflict in space, so you can orbit the framing and see the disagreement instead of reading about it. It is $499 per project on Pro — a per-project charge, which means it goes on the client invoice as "3D structural conflict review" like any other consultant scope. What you charge for it is your call. Passed through that way, the cost sits with the project rather than with your overhead.
See 3D mode →How many sets do you start a month?
Sized for 2 to 15 starts a year. Full reconciliation, drafted RFIs in three languages, stair module, crew and field access with no seat minimum, and 3D available per project.
Unlimited projects, team RFI workflow with status, Procore and ACC integration, 3D included, an audit trail for change-order disputes, and SSO.

Drop both sets. See the checklist. Send the RFI. Keep the adjudication where it belongs — with a person.
