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 946058). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early school construction cost planning in Mthatha, 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 Mthatha 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 Mthatha market basket or current school tenders. GeoNames 946058 records the locality at -31.5889, 28.7844, with snapshot population 164,848. That ranks Mthatha 44 of 50 listed places, while Mdantsane is the nearest listed peer at about 177 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 71.3 construction index mean?

The World Bank ICP 2021 construction PLI for South Africa is 71.3, 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 Mthatha costs 0.713 times a current world rate.

Which Mthatha inputs are known?

The reproducible locality point is -31.5889, 28.7844 (GeoNames 946058). Its snapshot population is 164,848, ranked 44 of 50 listed places; GeoNames classifies it as a populated place in administrative area 05. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Mthatha 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.

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.

Sources and method

National screening observation from the World Bank ICP 2021 API and ICP data documentation; locality and population from the GeoNames ZA dump (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 946058). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Frequently asked questions

Does the 71.3 index give a school cost per m² for Mthatha?

No. 71.3 is the World Bank ICP 2021 national construction price-level index for South Africa, with the world equal to 100. It is a cross-country screening statistic, not a Mthatha ZAR/m² rate, escalation index, quote or tender estimate.

How should a Mthatha school estimate replace this screening benchmark?

Collect current Mthatha comparables on a consistent gross-floor-area basis, reconcile teaching spaces, specialist rooms, safeguarding, sports provision and external works, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
