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 2176031). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early office construction cost planning in Berwick, 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 Berwick 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 Berwick market basket or current office tenders. GeoNames 2176031 records the locality at -38.0333, 145.3500, with snapshot population 50,298. That ranks Berwick 43 of 50 listed places, while Pakenham is the nearest listed peer at about 12 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 office work in Berwick costs 2.641 times a current world rate.

Which Berwick inputs are known?

The reproducible locality point is -38.0333, 145.3500 (GeoNames 2176031). Its snapshot population is 50,298, ranked 43 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 Berwick office project, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport. Use a consistent gross-floor-area basis and record the following before reliance.

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.

Sources and method

National screening observation from the World Bank ICP 2021 API and ICP data documentation; locality and population from the GeoNames AU dump (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 2176031). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Frequently asked questions

Does the 264.1 index give a office cost per m² for Berwick?

No. 264.1 is the World Bank ICP 2021 national construction price-level index for Australia, with the world equal to 100. It is a cross-country screening statistic, not a Berwick AUD/m² rate, escalation index, quote or tender estimate.

How should a Berwick office estimate replace this screening benchmark?

Collect current Berwick comparables on a consistent gross-floor-area basis, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
