Last updated September 15, 2026 · National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/ZAF/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 ZA dump](https://download.geonames.org/export/dump/ZA.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1016670). The PLI is not a city cost/m² rate, current escalation series or tender estimate.
Direct answer
For early school construction cost planning in Botshabelo, the World Bank ICP reports a 2021 South Africa construction price-level index of 71.3, with the world equal to 100. This is a national comparison—not a Botshabelo ZAR/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across South Africa in 2021; it does not measure a Botshabelo market basket or current school tenders. GeoNames 1016670 records the locality at -29.2674, 26.7260, with snapshot population 309,714. That ranks Botshabelo 24 of 50 listed places, while Bloemfontein is the nearest listed peer at about 52 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.

| Estimate field | Screening record | Project requirement |
|---|---|---|
| National context | ICP 2021 PLI 71.3 | Retain only as dated cross-country context |
| Local ZAR/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 × (71.3 ÷ P). At P = 100 the dimensionless ratio is 0.713; 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 | 71.3 (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 Botshabelo adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |
