# School Construction Cost Planning: Geylang, Singapore > Geylang school cost planning using the World Bank ICP 2021 national construction price-level index of 97.6, plus a GeoNames-based local comparable-search shortlist. - Canonical: https://harth.build/resources/construction-costs/school-construction-cost-geylang-sg/ - 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/SGP/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 SG dump](https://download.geonames.org/export/dump/SG.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1880668). The PLI is not a city cost/m² rate, current escalation series or tender estimate. ## Key facts | Fact | Value | | --- | --- | | National construction PLI | 97.6 (World Bank ICP 2021; World = 100) | | Screening ratio to world | 0.976 (dimensionless PLI ÷ 100; not a city location factor) | | Locality reference | 1.3195, 103.8869 (GeoNames ID 1880668) | | Snapshot population | 110,201 (23 of 50 listed Singapore places) | | Nearest listed peer | MacPherson · 1 km (great-circle distance between GeoNames reference points) | | Estimate currency | SGD (obtain a current local rate and named base date) | ## Direct answer For early school construction cost planning in Geylang, the World Bank ICP reports a 2021 Singapore construction price-level index of 97.6, with the world equal to 100. This is a national comparison—not a Geylang SGD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Singapore in 2021; it does not measure a Geylang market basket or current school tenders. GeoNames 1880668 records the locality at 1.3195, 103.8869, with snapshot population 110,201. That ranks Geylang 23 of 50 listed places, while MacPherson is the nearest listed peer at about 1 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 97.6 construction index mean? The World Bank ICP 2021 construction PLI for **Singapore is 97.6**, 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 Geylang costs 0.976 times a current world rate. ## Which Geylang inputs are known? The reproducible locality point is **1.3195, 103.8869** (GeoNames 1880668). Its snapshot population is **110,201**, ranked 23 of 50 listed places; GeoNames classifies it as a section of a populated place in administrative area 00. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Geylang 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 97.6 | Retain only as dated cross-country context | | Local SGD/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 | ## Geylang 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 Geylang | Snapshot population | Admin area | | --- | ---: | ---: | --- | | MacPherson | 1 | 26,850 | 01 | | Eunos | 1 | 32,820 | not stated | | Kallang | 3 | 101,290 | 00 | | Kembangan | 3 | 130,252 | 00 | | Marine Parade | 3 | 47,180 | 03 | | Sembawang Estate | 16 | 110,090 | 00 | | Serangoon New Town | 4 | 116,900 | 00 | | Serangoon | 5 | 116,900 | 00 | ## Price-level normalization worksheet For a validated reference rate **R** from a country with construction PLI **P**, the transparent screening calculation is **R × (97.6 ÷ P)**. At P = 100 the dimensionless ratio is 0.976; 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 | 97.6 (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 Geylang 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: Geylang, Singapore](https://harth.build/resources/construction-costs/office-construction-cost-geylang-sg.md) - [House Construction Cost Planning: Geylang, Singapore](https://harth.build/resources/construction-costs/house-construction-cost-geylang-sg.md) - [Retail Construction Cost Planning: Geylang, Singapore](https://harth.build/resources/construction-costs/retail-construction-cost-geylang-sg.md) - [School Construction Cost Planning: Eunos, Singapore](https://harth.build/resources/construction-costs/school-construction-cost-eunos-sg.md) - [All construction costs guidance for Singapore](https://harth.build/resources/construction-costs/singapore.md) - [Sun Path: Geylang, Singapore](https://harth.build/resources/solar-data/sun-path-geylang-sg.md) ## Sources and method National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/SGP/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 SG dump](https://download.geonames.org/export/dump/SG.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1880668).

No. 97.6 is the World Bank ICP 2021 national construction price-level index for Singapore, with the world equal to 100. It is a cross-country screening statistic, not a Geylang SGD/m² rate, escalation index, quote or tender estimate. ### How should a Geylang school estimate replace this screening benchmark? Collect current Geylang 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-geylang-sg%2F - View this page in a browser: https://harth.build/resources/construction-costs/school-construction-cost-geylang-sg/ - All resources for agents: https://harth.build/llms.txt
