Zaria office cost planning using the World Bank ICP 2021 national construction price-level index of 72.8, plus a GeoNames-based local comparable-search shortlist.

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 2317765). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early office construction cost planning in Zaria, 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 Zaria 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 Zaria market basket or current office tenders. GeoNames 2317765 records the locality at 11.1113, 7.7227, with snapshot population 980,000. That ranks Zaria 14 of 50 listed places, while Kaduna is the nearest listed peer at about 72 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 office work in Zaria costs 0.728 times a current world rate.

Which Zaria inputs are known?

The reproducible locality point is 11.1113, 7.7227 (GeoNames 2317765). Its snapshot population is 980,000, ranked 14 of 50 listed places; GeoNames classifies it as a populated place in administrative area 23. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Zaria office project, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport. 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 2317765). 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 office cost per m² for Zaria?

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

How should a Zaria office estimate replace this screening benchmark?

Collect current Zaria comparables on a consistent gross-floor-area basis, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
