## Key facts

| --- | --- |
| National construction PLI | 37.7 (World Bank ICP 2021; World = 100) |
| Screening ratio to world | 0.377 (dimensionless PLI ÷ 100; not a city location factor) |
| Locality reference | 22.5626, 88.3630 (GeoNames ID 1275004) |
| Snapshot population | 4,631,392 (7 of 50 listed India places) |
| Nearest listed peer | Jamshedpur · 225 km (great-circle distance between GeoNames reference points) |
| Estimate currency | INR (obtain a current local rate and named base date) |

## Direct answer

For early office construction cost planning in Kolkata, the World Bank ICP reports a 2021 India construction price-level index of 37.7, with the world equal to 100. This is a national comparison—not a Kolkata INR/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across India in 2021; it does not measure a Kolkata market basket or current office tenders. GeoNames 1275004 records the locality at 22.5626, 88.3630, with snapshot population 4,631,392. That ranks Kolkata 7 of 50 listed places, while Jamshedpur is the nearest listed peer at about 225 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 37.7 construction index mean?

The World Bank ICP 2021 construction PLI for **India is 37.7**, 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 Kolkata costs 0.377 times a current world rate.

## Which Kolkata inputs are known?

The reproducible locality point is **22.5626, 88.3630** (GeoNames 1275004). Its snapshot population is **4,631,392**, ranked 7 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area 28. These facts shape the local comparable search, not the price.

## What must a project estimate add?

For a Kolkata 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 37.7 | Retain only as dated cross-country context |
| Local INR/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 |

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 Kolkata | Snapshot population | Admin area |
| --- | ---: | ---: | --- |
| Jamshedpur | 225 | 1,339,438 | 38 |
| Dhanbad | 241 | 1,196,214 | 38 |
| Ranchi | 324 | 1,120,374 | 38 |
| Patna | 470 | 1,684,297 | 34 |
| Varanasi | 624 | 1,164,404 | 36 |
| Surat | 1,609 | 4,591,246 | 09 |
| Chennai | 1,356 | 4,681,087 | 25 |
| Ahmedabad | 1,617 | 6,357,693 | 09 |

## Price-level normalization worksheet

For a validated reference rate **R** from a country with construction PLI **P**, the transparent screening calculation is **R × (37.7 ÷ P)**. At P = 100 the dimensionless ratio is 0.377; 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 | 37.7 (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 Kolkata 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 37.7 index give a office cost per m² for Kolkata?

No. 37.7 is the World Bank ICP 2021 national construction price-level index for India, with the world equal to 100. It is a cross-country screening statistic, not a Kolkata INR/m² rate, escalation index, quote or tender estimate.

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

Collect current Kolkata 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.
