Machines read drawings, borehole reports, and calculations, and turn them into judgments with the evidence linked and the standard verified.
Floor-plan window marks ↔ window schedule, fully cross-checked
Evidence original plan coordinates · per-mark crop attached
Rule window-schedule matching rule · version-pinned
Approval pending reviewer — the AI does not approve

doAZ produces not a plausible answer, but a result linked to its evidence.
Machines read drawings and documents, and cross-check consistency across them.
Every judgment carries its source coordinate, clause, and confidence.
Official calculation runs on a version-pinned deterministic engine — the LLM never does the math.
When evidence is weak, the AI abstains first and hands off to a person.
Designed for on-premise and air-gapped deployment.
Industrial Knowledge to Actionable AI. Understand. Compile. Verify. Operate.
It’s the question we hear the most. General-purpose AI produces plausible answers. In engineering review, plausible is not the same as correct — and a wrong basis only surfaces after the audit or the incident.
Above all — it doesn’t say so, even when it’s wrong.
And — when evidence is weak, it abstains first and hands the item to a person.
The doAZ Engine unifies an AI reasoning layer and an engineering precision layer into one structure — not AI bolted onto existing tools, but a platform designed around verification from the ground up.
Understands the industrial meaning of documents, drawings, tables, and calculations. It extracts, proposes mappings, and retrieves evidence to explain its reasoning — a domain-adaptive structure that even learns office-specific notation conventions.
Official calculations run on a version-pinned deterministic engine. Units, standards, tolerances, tests, and approval history are managed as a single executable unit.

Reads bridge and tunnel drawing sets sheet by sheet, structures design conditions, members and quantities, and links schedule analysis to evidence coordinates on the drawing.
An engineering AX strategy for water-treatment and desalination plants, built together — turning the knowledge held in standards and drawings into verifiable action, from planning to phased execution.
Engineering calculations for the SPM project.
Cross-checks apartment design documents — drawings, schedules and standards — end to end, and hands nonconformity candidates to reviewers with evidence.

AI review of pre-work safety assessments for high-risk work — advisory-only, so approvals are supported, never blocked.
