Last updated September 15, 2026 · National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/AUS/classification/PX.WL/series/1501200/time/YR2021/data?format=json) and [ICP data documentation](https://www.worldbank.org/en/programs/icp/data); locality and population from the [GeoNames AU dump](https://download.geonames.org/export/dump/AU.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 2147357). The PLI is not a city cost/m² rate, current escalation series or tender estimate.
Direct answer
For early school construction cost planning in Tarneit, the World Bank ICP reports a 2021 Australia construction price-level index of 264.1, with the world equal to 100. This is a national comparison—not a Tarneit AUD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Australia in 2021; it does not measure a Tarneit market basket or current school tenders. GeoNames 2147357 records the locality at -37.8363, 144.6595, with snapshot population 56,370. That ranks Tarneit 38 of 50 listed places, while Werribee is the nearest listed peer at about 7 km. Use these facts only to plan the comparable search. Obtain current local rates on a consistent area basis, then reconcile scope, taxes, fees, contingency and escalation. Retain the source, base date and reviewer when local evidence replaces the screening ratio.

What does the 264.1 construction index mean?
The World Bank ICP 2021 construction PLI for Australia is 264.1, compared with a world benchmark of 100. It is a national spatial price comparison assembled for the 2021 reference year. It does not say that school work in Tarneit costs 2.641 times a current world rate.
Which Tarneit inputs are known?
The reproducible locality point is -37.8363, 144.6595 (GeoNames 2147357). Its snapshot population is 56,370, ranked 38 of 50 listed places; GeoNames classifies it as a section of a populated place in administrative area 07. These facts shape the local comparable search, not the price.
What must a project estimate add?
For a Tarneit school project, reconcile teaching spaces, specialist rooms, safeguarding, sports provision and external works. Use a consistent gross-floor-area basis and record the following before reliance.
| Estimate field | Screening record | Project requirement |
|---|---|---|
| National context | ICP 2021 PLI 264.1 | Retain only as dated cross-country context |
| Local AUD/m² rate | Not supplied | Current comparable with named source and base date |
| Area and scope | Gross floor area; scope unresolved | Measurement standard, specification and procurement route |
| Additions | Not supplied | Taxes, fees, site work, contingency and escalation |
| Review | Automated source and arithmetic QA | Qualified local cost review |

Price-level normalization worksheet
For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (264.1 ÷ P). At P = 100 the dimensionless ratio is 2.641; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.
| Input | Recorded value | Release condition |
|---|---|---|
| Target national PLI | 264.1 (World = 100, 2021) | Screening context only |
| Reference construction PLI P | User-supplied from the same ICP classification/year | Must match reference rate country |
| Validated reference rate R | User-supplied | Named source, currency, date, area and scope |
| Local Tarneit adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |
