Last updated September 15, 2026 · 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 1880283). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early house construction cost planning in Sembawang Estate, 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 Sembawang Estate 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 Sembawang Estate market basket or current house tenders. GeoNames 1880283 records the locality at 1.4508, 103.8286, with snapshot population 110,090. That ranks Sembawang Estate 24 of 50 listed places, while Yishun New Town is the nearest listed peer at about 2 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.

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.
