## Key facts

| Fact | Value |
| --- | --- |
| National construction PLI | 152.8 (World Bank ICP 2021; World = 100) |
| Screening ratio to world | 1.528 (dimensionless PLI ÷ 100; not a city location factor) |
| Locality reference | 53.2953, -6.3089 (GeoNames ID 3315404) |
| Snapshot population | 18,076 (35 of 50 listed Ireland places) |
| Nearest listed peer | Rathfarnham · 2 km (great-circle distance between GeoNames reference points) |
| Estimate currency | EUR (obtain a current local rate and named base date) |

## Direct answer

For early office construction cost planning in Templeogue, the World Bank ICP reports a 2021 Ireland construction price-level index of 152.8, with the world equal to 100. This is a national comparison—not a Templeogue EUR/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Ireland in 2021; it does not measure a Templeogue market basket or current office tenders. GeoNames 3315404 records the locality at 53.2953, -6.3089, with snapshot population 18,076. That ranks Templeogue 35 of 50 listed places, while Rathfarnham 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.

## What does the 152.8 construction index mean?

The World Bank ICP 2021 construction PLI for **Ireland is 152.8**, 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 office work in Templeogue costs 1.528 times a current world rate.

## Which Templeogue inputs are known?

The reproducible locality point is **53.2953, -6.3089** (GeoNames 3315404). Its snapshot population is **18,076**, ranked 35 of 50 listed places; GeoNames classifies it as a section of a populated place in administrative area L. These facts shape the local comparable search, not the price.

## What must a project estimate add?

For a Templeogue office project, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport. Use a consistent gross-floor-area basis and record the following before reliance.

| Estimate field | Screening record | Project requirement |
| --- | --- | --- |
| National context | ICP 2021 PLI 152.8 | Retain only as dated cross-country context |
| Local EUR/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 × (152.8 ÷ P)**. At P = 100 the dimensionless ratio is 1.528; 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 | 152.8 (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 Templeogue 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 152.8 index give a office cost per m² for Templeogue?

No. 152.8 is the World Bank ICP 2021 national construction price-level index for Ireland, with the world equal to 100. It is a cross-country screening statistic, not a Templeogue EUR/m² rate, escalation index, quote or tender estimate.

### How should a Templeogue office estimate replace this screening benchmark?

Collect current Templeogue comparables on a consistent gross-floor-area basis, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
