What does CAT stand for?

Council As-built Template. It's CCC's Excel template for delivering electronic as-built asset data, complying with IDS Part 12 and the SAG (CCC, As-built survey and data requirements).

Are CAT sheets actually required, or just nice to have?

Required. IDS Part 12: "Where required by a condition of contract or as a condition of subdivision consent provide as-built records," delivered "electronically using the CAT" (CCC, IDS Part 12).

Which template do I use?

Reticulation (water/wastewater/stormwater), Stations (pump stations/plants), Land Improvement (parks/recreation), Land Drainage (open waterways), plus the Council Disposal Sheet for removed assets. Confirm with your CCC project manager before fieldwork, because the wrong template causes rework (CCC, IDS Part 12). See Article 2.

What datum do I use?

Vertical: NZVD2016 (mandatory - old datum = can't be processed). Horizontal: Mt Pleasant 2000 (NZGD2000) (CCC, As-built survey and data requirements; IDS Part 12). See Article 3.

Can I just use GNSS/GPS for everything?

No - the SAG states the survey-accurate tolerances (e.g. inverts to ±10 mm in height) "cannot be reached using GPS devices." Use conventional survey methods for inverts and chamber levels (CCC, Survey As-built Guideline).

How do I submit?

Reticulation and Land Improvement CATs go through the online as-built data portal (an FME portal that validates then accepts your data). Stations CATs go by email to the project manager / contract engineer; land-drainage and disposal items also go by email (CCC, As-built data portal; As-built survey and data requirements). See Article 4.

How do I get portal access?

Use CCC's "Request portal access" page to "Request FME Portal access, reset your password or cancel your access." Do it early (CCC, Request portal access).

What else do I submit besides the spreadsheet?

Per the SAG: the CAT, red-line marked-up drawings (every page signed and dated, even if "no changes"), a survey as-built report, and the Stations Asset Pickup Sheet for stations work (CCC, Survey As-built Guideline).

What happens to the data?

It feeds CCC's asset records and the public three-waters network maps, and underpins property/LIM information used by future buyers (CCC, Three waters asset network map; LIM).

Where do I get the templates and the rules?

Everything is on CCC's "As-built survey and data requirements" page - templates, worked examples, the SAG and its appendices, change logs, the FAQ and the glossary. Always download the latest version.

Two things this resource can't fully verify (be aware): (1) the exact validation behaviour inside the portal SOPs (errors vs warnings) - check CCC's SOP PDFs directly; (2) CCC publishes an official "As-built information FAQs" PDF and glossary PDF on the as-built page - read these for CCC's own definitions of terms like invert level, UID and location certainty.
