Last updated September 15, 2026 · National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/NGA/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 NG dump](https://download.geonames.org/export/dump/NG.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 2320576). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early school construction cost planning in Umuahia, the World Bank ICP reports a 2021 Nigeria construction price-level index of 72.8, with the world equal to 100. This is a national comparison—not a Umuahia NGN/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Nigeria in 2021; it does not measure a Umuahia market basket or current school tenders. GeoNames 2320576 records the locality at 5.5249, 7.4946, with snapshot population 370,000. That ranks Umuahia 41 of 50 listed places, while Aba is the nearest listed peer at about 49 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 72.8 construction index mean?

The World Bank ICP 2021 construction PLI for Nigeria is 72.8, 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 Umuahia costs 0.728 times a current world rate.

Which Umuahia inputs are known?

The reproducible locality point is 5.5249, 7.4946 (GeoNames 2320576). Its snapshot population is 370,000, ranked 41 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area 45. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Umuahia 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 × (72.8 ÷ P). At P = 100 the dimensionless ratio is 0.728; 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 NG dump (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 2320576). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Frequently asked questions

Does the 72.8 index give a school cost per m² for Umuahia?

No. 72.8 is the World Bank ICP 2021 national construction price-level index for Nigeria, with the world equal to 100. It is a cross-country screening statistic, not a Umuahia NGN/m² rate, escalation index, quote or tender estimate.

How should a Umuahia school estimate replace this screening benchmark?

Collect current Umuahia 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.
