ARRO · RFI intelligence

The RFI
engine.

A source-linked model of what New Zealand councils ask for, organised by clause, discipline, location, and evidence type. It powers both pre-lodgement flags and cited RFI response drafts.

Corpus distribution

726 triggers, not one generic checklist.

The corpus is weighted toward the disciplines that generate the most documented questions: structure, services, fire, and weathertightness. The long tail is retained rather than hidden, because accessibility, H1, planning, and site conditions still change what evidence a council expects.

Provenance

Every result has somewhere to point.

ARRO does not present public MBIE and council material as a private dataset. Publisher, document, page or section, and the supporting text stay attached to each structured record.

Outputs are review aids. The project team remains responsible for the final technical and regulatory decision.

Evidence chain

From public record to reviewable output.

One evidence pipeline supports both sides of the product. Before lodgement it helps rank likely issues on a drawing; after an RFI arrives it helps ground the response against the submitted project record.

01

Collect

Published council guidance, check sheets, MBIE determinations, Building Code material, and regional policy text.

02

Structure

Each trigger is classified by council, discipline, clause, project context, and the evidence commonly requested.

03

Match

The engine compares a drawing finding or incoming RFI with the closest relevant, council-specific evidence.

04

Cite

The output keeps its source trail so a reviewer can inspect the basis, edit the response, and make the final call.
