## Key facts

| Fact | Value |
| --- | --- |
| National construction PLI | 264.1 (World Bank ICP 2021; World = 100) |
| Screening ratio to world | 2.641 (dimensionless PLI ÷ 100; not a city location factor) |
| Locality reference | -34.9287, 138.5986 (GeoNames ID 2078025) |
| Snapshot population | 1,469,163 (5 of 50 listed Australia places) |
| Nearest listed peer | Adelaide Hills · 10 km (great-circle distance between GeoNames reference points) |
| Estimate currency | AUD (obtain a current local rate and named base date) |

## Direct answer

For early house construction cost planning in Adelaide, 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 Adelaide 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 Adelaide market basket or current house tenders. GeoNames 2078025 records the locality at -34.9287, 138.5986, with snapshot population 1,469,163. That ranks Adelaide 5 of 50 listed places, while Adelaide Hills is the nearest listed peer at about 10 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 house work in Adelaide costs 2.641 times a current world rate.

## Which Adelaide inputs are known?

The reproducible locality point is **-34.9287, 138.5986** (GeoNames 2078025). Its snapshot population is **1,469,163**, ranked 5 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area 05. These facts shape the local comparable search, not the price.

## What must a project estimate add?

For a Adelaide house project, reconcile dwelling size, structural system, envelope specification, kitchens and bathrooms. 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 |

This shortlist is computed from the checked GeoNames snapshot. Distance and population help prioritize where to request comparables; neither is used as a cost multiplier.

| Adelaide Hills | 10 | 72,260 | 05 |
| Bendigo | 551 | 103,034 | 07 |
| Ballarat | 555 | 111,973 | 07 |
| Geelong | 627 | 282,809 | 07 |

| Gold Coast | 1,601 | 640,778 | 04 |

## 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 Adelaide adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |

## Frequently asked questions

### Does the 264.1 index give a house cost per m² for Adelaide?

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 Adelaide AUD/m² rate, escalation index, quote or tender estimate.

### How should a Adelaide house estimate replace this screening benchmark?

Collect current Adelaide comparables on a consistent gross-floor-area basis, reconcile dwelling size, structural system, envelope specification, kitchens and bathrooms, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
