Direct answer

For early retail construction cost planning in Narok, the World Bank ICP reports a 2021 Kenya construction price-level index of 64.9, with the world equal to 100. This is a national comparison—not a Narok KES/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Kenya in 2021; it does not measure a Narok market basket or current retail tenders. GeoNames 184379 records the locality at -1.0808, 35.8711, with snapshot population 65,430. That ranks Narok 43 of 50 listed places, while Naivasha is the nearest listed peer at about 75 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 64.9 construction index mean?

The World Bank ICP 2021 construction PLI for Kenya is 64.9, 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 retail work in Narok costs 0.649 times a current world rate.

Which Narok inputs are known?

The reproducible locality point is -1.0808, 35.8711 (GeoNames 184379). Its snapshot population is 65,430, ranked 43 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area 41. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Narok retail project, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord 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 64.9	Retain only as dated cross-country context
Local KES/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 × (64.9 ÷ P). At P = 100 the dimensionless ratio is 0.649; 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	64.9 (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 Narok 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 64.9 index give a retail cost per m² for Narok?

No. 64.9 is the World Bank ICP 2021 national construction price-level index for Kenya, with the world equal to 100. It is a cross-country screening statistic, not a Narok KES/m² rate, escalation index, quote or tender estimate.

How should a Narok retail estimate replace this screening benchmark?

Collect current Narok comparables on a consistent gross-floor-area basis, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
