BetaBuilt for Australian EngineersBeta
AI for structural engineering that shows its working.
Draft engineering documents for you to check and sign, navigate NCC 2025, and screen a site for the hazards our maps cover — purpose-built for Australian construction professionals.
Free tier includes 25 CodeLens queries per month and 10 questions about your project files per month (Files tab, launching soon). No credit card required.

Codes and standards our tools refer to
We refer to Australian Standards by name, designation and clause number only, and show none of their text, values or requirements. Our NCC 2025 entries are summaries of ABCB material published under CC BY 4.0. Buy the full text of a standard from Standards Australia. How we use standards.
- NCC 2025
- AS 3600 — Concrete
- AS 4100 — Steel
- AS/NZS 1170 — Loads
- AS 1720 — Timber
- AS 2870 — Footings
- AS 3959 — Bushfire
- AS 4055 — Wind
Platform
5 modules. One platform.
Every tool available to Australian structural engineers today. Each one states what it does and what it cannot before you start.
EngiDocs AI
Draft design reports, certificates and specifications in minutes, citing AS / NCC references for you to check before you sign.
CodeLens AU
Ask about NCC 2025 in plain English and get an answer built from our summaries that shows which ones it used.
TenderForge AU
Pull the requirements out of a tender pack, sorted by category, with the lines it could not read listed for you to check. Then draft a response for you to finish with what your business has done.
StructCheck AI
Extract structural members from CAD drawings (DXF, PDF, IFC) and run completeness checks plus StructByAI's own screening heuristics. No check in this build is sourced from a standard.
SiteIQ AI
Screen a site in one pass: every hazard it could assess for the address, and a plain "not assessed" for any it could not.
Why engineers trust it
Built to show its working, not to sound sure.
An AI tool is only useful to an engineer if you can check it. Answers and documents name the sources they cite, and show what our check of them found. An answer can still rest on partial retrieval, so treat it as a starting point.
Answers from our entries
Answers are drawn from our summaries of NCC 2025 and our pointers to Australian Standards, and list the ones they used; an answer that cites none is refused. Where our entries don't cover your question, the AI is told to say so rather than guess.
Citations checked against our entries
Clause references are checked against our own entries (NCC summaries, and Australian Standards pointers that hold none of their text), not the published standards, and marked with what we found. When the check can't run, they are marked "Not checked".
Blanks stay blank
A design value you didn't supply is left as a marked placeholder, and numbers with units the AI wrote itself are marked for you to confirm.
Requirements, not sign-off
If the AI writes that a design complies, the sentence is put into requirement voice where possible, and otherwise flagged in a caution — or, in a certificate, removed. The judgement stays with the engineer who signs.
Workflow
From setup to a draft you check and sign
Three steps. Drafts for your review. Sources you can trace.
01
Create a Project
Set up your project with location, structure type, and design parameters. Your account's country sets which standards the modules draw on.
02
Generate & Query
Draft engineering documents for your review, ask questions about NCC 2025, or screen a site for the hazards our maps cover.
03
Review & Export
Review the draft and the standards it cites, check them against the published editions, edit as needed, and export to PDF.
National Reach
Open in every state and territory; local data only where stated
StructBy AI works from our summaries of NCC 2025 and refers to Australian Standards by name, designation and clause number only. It reads bushfire maps for New South Wales, Victoria, Western Australia, Tasmania and the ACT and flood planning maps for Victoria and Tasmania, each where the map covers the site, and state variations only where our NCC summaries note them — confirm local rules with the relevant authority.
- New South Wales
- Victoria
- Queensland
- South Australia
- Western Australia
- Tasmania
- Northern Territory
- Australian Capital Territory
