Featured Tools

  Knowledge Agent (for NZ engineering)

Chat with an AI that cites New Zealand standards and guidance documents.


How it works

  1. Ask — describe your scenario, and relevant clauses if known
  2. Review — the agent drafts an answer and surfaces clause-level citations.
  3. Verify — a qualified engineer must check against current standards and project conditions.


Sources we cite

  • AS/NZS 1170 series
  • Waka Kotahi Bridge Manual
  • Material standards such as NZS 3101 (Concrete)
  • other NZ standards


What it’s great at

  • Explaining clauses in plain language with clause numbers
  • Drafting checklists and design notes aligned to NZ practice
  • Pointing to relevant sections and typical pitfalls


Sample Q&A

Q: Minimum cover for a cast-in-place RC beam in coastal sea-spray?
A: The Agent selects the exposure class and returns the minimum cover (mm) from NZS 3101 with a clause citation.


Legal note

This agent provides preliminary guidance only and does not constitute professional engineering advice or producer statements (PS1/PS2). A suitably qualified engineer must verify all outputs against the latest standards and project conditions. See our Terms and Privacy Policy.
