# School Construction Cost Planning: Peng Siang, Singapore > Peng Siang 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-peng-siang-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 13118139). 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 | 1.3800, 103.7407 (GeoNames ID 13118139) | | Snapshot population | 33,860 (40 of 50 listed Singapore places) | | Nearest listed peer | Keat Hong Village · 0 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 Peng Siang, 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 Peng Siang 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 Peng Siang market basket or current school tenders. GeoNames 13118139 records the locality at 1.3800, 103.7407, with snapshot population 33,860. That ranks Peng Siang 40 of 50 listed places, while Keat Hong Village is the nearest listed peer at about 0 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 Peng Siang costs 0.976 times a current world rate. ## Which Peng Siang inputs are known? The reproducible locality point is **1.3800, 103.7407** (GeoNames 13118139). Its snapshot population is **33,860**, ranked 40 of 50 listed places; GeoNames classifies it as a section of a populated place in administrative area not stated. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Peng Siang 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 | ## Peng Siang 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 Peng Siang | Snapshot population | Admin area | | --- | ---: | ---: | --- | | Keat Hong Village | 0 | 39,370 | 00 | | Choa Chu Kang New Town | 1 | 187,550 | 03 | | Yew Tee | 2 | 39,100 | 03 | | Jelebu | 2 | 29,960 | not stated | | Bukit Panjang New Town | 3 | 138,050 | 05 | | Eunos | 19 | 32,820 | not stated | | Kangkar | 18 | 32,290 | 00 | | Serangoon Garden | 13 | 36,080 | 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 Peng Siang 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: Peng Siang, Singapore](https://harth.build/resources/construction-costs/office-construction-cost-peng-siang-sg.md) - [House Construction Cost Planning: Peng Siang, Singapore](https://harth.build/resources/construction-costs/house-construction-cost-peng-siang-sg.md) - [Retail Construction Cost Planning: Peng Siang, Singapore](https://harth.build/resources/construction-costs/retail-construction-cost-peng-siang-sg.md) - [School Construction Cost Planning: Keat Hong Village, Singapore](https://harth.build/resources/construction-costs/school-construction-cost-keat-hong-village-sg.md) - [All construction costs guidance for Singapore](https://harth.build/resources/construction-costs/singapore.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 13118139).

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 Peng Siang SGD/m² rate, escalation index, quote or tender estimate. ### How should a Peng Siang school estimate replace this screening benchmark? Collect current Peng Siang 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-peng-siang-sg%2F - View this page in a browser: https://harth.build/resources/construction-costs/school-construction-cost-peng-siang-sg/ - All resources for agents: https://harth.build/llms.txt
