Direct answer

For early school construction cost planning in Yola, 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 Yola 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 Yola market basket or current school tenders. GeoNames 2318044 records the locality at 9.2084, 12.4815, with snapshot population 460,000. That ranks Yola 32 of 50 listed places, while Gombe is the nearest listed peer at about 188 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 Yola costs 0.728 times a current world rate.

Which Yola inputs are known?

The reproducible locality point is 9.2084, 12.4815 (GeoNames 2318044). Its snapshot population is 460,000, ranked 32 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area 35. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Yola 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.

Estimate field	Screening record	Project requirement
National context	ICP 2021 PLI 72.8	Retain only as dated cross-country context
Local NGN/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 × (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.

Input	Recorded value	Release condition
Target national PLI	72.8 (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 Yola 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 72.8 index give a school cost per m² for Yola?

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 Yola NGN/m² rate, escalation index, quote or tender estimate.

How should a Yola school estimate replace this screening benchmark?

Collect current Yola 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.
