Predict the RFI.
Draft the reply.
Every RFI, end to end. ARRO flags the items likely to draw a council RFI before you lodge, then reads the letters that do arrive and drafts council-ready responses - grounded in the real RFI practice of 40 New Zealand councils.
Pre-emptively flag your drawings for RFIs
Upload your drawing set and ARRO reviews it the way a council vetter would - surfacing the items likely to draw an RFI before you lodge. Every flag sits on the exact region of the sheet that raised it, tied to the NZBC clause it breaches, so your team can clear the list before the council ever sees it.
- Numbered, severity-graded flags pinned to the drawing region
- Each finding tied to an NZBC clause and MBIE Acceptable Solution
- A verifier pass keeps the list short and worth reading
- Multi-sheet PDF and specification ingest with sheet tracking
Our RFI auto-response tool drafts the reply
When a council RFI lands, drop in the letter. ARRO extracts every ask, classifies it to its Building Code clause, grounds it against the plans and specs you actually submitted, and drafts a council-ready response with citations - hours, not weeks.
- Every numbered item extracted and interpreted in plain English
- Each ask grounded against your submitted drawings and specs
- A council-ready reply drafted with a citation on every claim
- Exported as a lodgement-ready bundle

Questions we get asked
Which councils does the RFI Engine cover?
It's grounded in the real RFI practice of 40 New Zealand councils - 726 documented RFI triggers across 42 NZBC clauses and 464 regional overlay requirements - with the deepest, most operational coverage across Canterbury's three BCAs: Christchurch City, Selwyn, and Waimakariri.
How does the pre-lodgement flagging work?
Upload your drawing set and ARRO reviews it the way a council vetter would, surfacing the items likely to draw an RFI before you lodge. Every flag is pinned to the exact region of the sheet that raised it and tied to the NZBC clause it breaches.
What happens when an RFI letter actually arrives?
Drop in the letter and ARRO extracts every ask, classifies it to its Building Code clause, grounds it against the plans and specs you actually submitted, and drafts a council-ready response with a citation on every claim - exported as a lodgement-ready bundle.
Is this just a checker, or does it draft the response too?
Both. ARRO flags likely RFI triggers before you lodge, and for RFIs that do land, it reads the letter, grounds each ask against your submitted drawings, and drafts the reply - not just a findings list.
