# Office Construction Cost Planning: Tarlac City, Philippines > Tarlac City office cost planning using the World Bank ICP 2021 national construction price-level index of 49.3, plus a GeoNames-based local comparable-search shortlist. - Canonical: https://harth.build/resources/construction-costs/office-construction-cost-tarlac-city-ph/ - 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/PHL/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 PH dump](https://download.geonames.org/export/dump/PH.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1682812). The PLI is not a city cost/m² rate, current escalation series or tender estimate. ## Key facts | Fact | Value | | --- | --- | | National construction PLI | 49.3 (World Bank ICP 2021; World = 100) | | Screening ratio to world | 0.493 (dimensionless PLI ÷ 100; not a city location factor) | | Locality reference | 15.4802, 120.5979 (GeoNames ID 1682812) | | Snapshot population | 401,892 (31 of 50 listed Philippines places) | | Nearest listed peer | Santol · 36 km (great-circle distance between GeoNames reference points) | | Estimate currency | PHP (obtain a current local rate and named base date) | ## Direct answer For early office construction cost planning in Tarlac City, the World Bank ICP reports a 2021 Philippines construction price-level index of 49.3, with the world equal to 100. This is a national comparison—not a Tarlac City PHP/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Philippines in 2021; it does not measure a Tarlac City market basket or current office tenders. GeoNames 1682812 records the locality at 15.4802, 120.5979, with snapshot population 401,892. That ranks Tarlac City 31 of 50 listed places, while Santol is the nearest listed peer at about 36 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 49.3 construction index mean? The World Bank ICP 2021 construction PLI for **Philippines is 49.3**, 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 Tarlac City costs 0.493 times a current world rate. ## Which Tarlac City inputs are known? The reproducible locality point is **15.4802, 120.5979** (GeoNames 1682812). Its snapshot population is **401,892**, ranked 31 of 50 listed places; GeoNames classifies it as a second-order administrative seat in administrative area 03. These facts shape the local comparable search, not the price. ## What must a project estimate add? For a Tarlac City 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 49.3 | Retain only as dated cross-country context | | Local PHP/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 | ## Tarlac City 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 Tarlac City | Snapshot population | Admin area | | --- | ---: | ---: | --- | | Santol | 36 | 298,976 | 03 | | Angeles City | 37 | 483,452 | 03 | | Cabanatuan City | 39 | 343,672 | 03 | | Malolos | 74 | 269,809 | 03 | | San Jose del Monte | 88 | 357,828 | 03 | | Pasay | 113 | 416,522 | NCR | | Cotabato | 1,000 | 383,383 | 14 | | Mandaluyong | 111 | 425,000 | NCR | ## Price-level normalization worksheet For a validated reference rate **R** from a country with construction PLI **P**, the transparent screening calculation is **R × (49.3 ÷ P)**. At P = 100 the dimensionless ratio is 0.493; 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 | 49.3 (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 Tarlac City 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) - [House Construction Cost Planning: Tarlac City, Philippines](https://harth.build/resources/construction-costs/house-construction-cost-tarlac-city-ph.md) - [School Construction Cost Planning: Tarlac City, Philippines](https://harth.build/resources/construction-costs/school-construction-cost-tarlac-city-ph.md) - [Retail Construction Cost Planning: Tarlac City, Philippines](https://harth.build/resources/construction-costs/retail-construction-cost-tarlac-city-ph.md) - [Office Construction Cost Planning: Santol, Philippines](https://harth.build/resources/construction-costs/office-construction-cost-santol-ph.md) - [All construction costs guidance for Philippines](https://harth.build/resources/construction-costs/philippines.md) - [Climate Design Data: Tarlac City, Philippines](https://harth.build/resources/climate-data/climate-design-data-tarlac-city-ph.md) - [Sun Path: Tarlac City, Philippines](https://harth.build/resources/solar-data/sun-path-tarlac-city-ph.md) ## Sources and method National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/PHL/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 PH dump](https://download.geonames.org/export/dump/PH.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 1682812).

No. 49.3 is the World Bank ICP 2021 national construction price-level index for Philippines, with the world equal to 100. It is a cross-country screening statistic, not a Tarlac City PHP/m² rate, escalation index, quote or tender estimate. ### How should a Tarlac City office estimate replace this screening benchmark? Collect current Tarlac City 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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fconstruction-costs%2Foffice-construction-cost-tarlac-city-ph%2F - View this page in a browser: https://harth.build/resources/construction-costs/office-construction-cost-tarlac-city-ph/ - All resources for agents: https://harth.build/llms.txt
