# School Construction Cost Planning: Ijebu Ode, Nigeria > Ijebu Ode school cost planning using the World Bank ICP 2021 national construction price-level index of 72.8, plus a GeoNames-based local comparable-search shortlist. - Canonical: https://harth.build/resources/construction-costs/school-construction-cost-ijebu-ode-ng/ - Last updated: 2026-09-15 - Data source: 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 2338400). The PLI is not a city cost/m² rate, current escalation series or tender estimate. ## Key facts | Fact | Value | | --- | --- | | National construction PLI | 72.8 (World Bank ICP 2021; World = 100) | | Screening ratio to world | 0.728 (dimensionless PLI ÷ 100; not a city location factor) | | Locality reference | 6.8194, 3.9173 (GeoNames ID 2338400) | | Snapshot population | 360,000 (45 of 50 listed Nigeria places) | | Nearest listed peer | Ebute Ikorodu · 53 km (great-circle distance between GeoNames reference points) | | Estimate currency | NGN (obtain a current local rate and named base date) | ## Direct answer For early school construction cost planning in Ijebu Ode, 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 Ijebu Ode 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 Ijebu Ode market basket or current school tenders. GeoNames 2338400 records the locality at 6.8194, 3.9173, with snapshot population 360,000. That ranks Ijebu Ode 45 of 50 listed places, while Ebute Ikorodu is the nearest listed peer at about 53 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. *Content and cited inputs reviewed by [Scott Barrington](https://nz.linkedin.com/in/barrington), Harth founder and architectural technology specialist · Published 2026-08-26 · Updated 2026-09-15.* ## 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 Ijebu Ode costs 0.728 times a current world rate. ## Which Ijebu Ode inputs are known? The reproducible locality point is **6.8194, 3.9173** (GeoNames 2338400). Its snapshot population is **360,000**, ranked 45 of 50 listed places; GeoNames classifies it as a second-order administrative seat in administrative area 16. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Ijebu Ode 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 | ## Ijebu Ode comparable-location search screen This shortlist is computed from the checked GeoNames snapshot. Distance and population help prioritize where to request comparables; neither is used as a cost multiplier. | Listed place | Great-circle km from Ijebu Ode | Snapshot population | Admin area | | --- | ---: | ---: | --- | | Ebute Ikorodu | 53 | 535,619 | 05 | | Ibadan | 62 | 3,649,000 | 32 | | Lekki | 64 | 401,272 | 05 | | Ikeja | 68 | 313,196 | 05 | | Agege | 68 | 683,600 | 05 | | Yenagoa | 334 | 365,000 | 52 | | Gboko | 564 | 365,000 | 26 | | Iseyin | 133 | 365,300 | 32 | ## 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 Ijebu Ode adjustment | Not asserted | Replace with current local comparable evidence | | Result status | Screening normalization | Not a budget, quote or tender estimate | ## Where can you explore related guidance? - [Explore all construction costs guidance](https://harth.build/resources/construction-costs.md) - [Office Construction Cost Planning: Ijebu Ode, Nigeria](https://harth.build/resources/construction-costs/office-construction-cost-ijebu-ode-ng.md) - [House Construction Cost Planning: Ijebu Ode, Nigeria](https://harth.build/resources/construction-costs/house-construction-cost-ijebu-ode-ng.md) - [Retail Construction Cost Planning: Ijebu Ode, Nigeria](https://harth.build/resources/construction-costs/retail-construction-cost-ijebu-ode-ng.md) - [School Construction Cost Planning: Ebute Ikorodu, Nigeria](https://harth.build/resources/construction-costs/school-construction-cost-ebute-ikorodu-ng.md) - [All construction costs guidance for Nigeria](https://harth.build/resources/construction-costs/nigeria.md) - [Climate Design Data: Ijebu Ode, Nigeria](https://harth.build/resources/climate-data/climate-design-data-ijebu-ode-ng.md) - [Sun Path: Ijebu Ode, Nigeria](https://harth.build/resources/solar-data/sun-path-ijebu-ode-ng.md) ## Sources and method 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 2338400).

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 Ijebu Ode NGN/m² rate, escalation index, quote or tender estimate. ### How should a Ijebu Ode school estimate replace this screening benchmark? Collect current Ijebu Ode 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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fconstruction-costs%2Fschool-construction-cost-ijebu-ode-ng%2F - View this page in a browser: https://harth.build/resources/construction-costs/school-construction-cost-ijebu-ode-ng/ - All resources for agents: https://harth.build/llms.txt
