The PLI is not a city cost/m² rate, current escalation series or tender estimate.
Direct answer
For early house construction cost planning in Ma On Shan, the World Bank ICP reports a 2021 Hong Kong SAR, China construction price-level index of 141.8, with the world equal to 100. This is a national comparison—not a Ma On Shan HKD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Hong Kong SAR, China in 2021; it does not measure a Ma On Shan market basket or current house tenders. GeoNames 1819400 records the locality at 22.4061, 114.2408, with snapshot population 215,200. That ranks Ma On Shan 17 of 50 listed places, while Sai Kung is the nearest listed peer at about 4 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 × (141.8 ÷ P). At P = 100 the dimensionless ratio is 1.418; 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 | 141.8 (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 Ma On Shan adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |
