# Projektometr

> Projektometr is a neutral, non-partisan database of Polish megaprojects (investments ≥ PLN 500 million
> or strategic). Behind every fact — cost, status, deadlines, what was built and what failed — there is
> a source link. Bilingual (Polish default, English). Nominal costs (prices from various years).

Projektometr was built to separate hard facts from the scattered noise of news and social media: what Poland
is really building, checked against sources. The goal — that the reader (and an AI assistant) can verify
for themselves, rather than trust a narrative.

## State and updates

- As of: July 2026 (last verified 2026-07-19).
- Updates: monthly (re-verification of records that may have changed, plus new entries).
- Records: 228 (203 contemporary since 2020 + 25 earlier landmarks).

## Rules (methodology)

- No source → no claim. Every grounded field has a quote + URL + retrieval date.
- Success isn't binary: separate axes (delivery / schedule / budget / utilisation).
- Failures shown with the same rigour as successes.
- "Value-by-stage", NOMINAL (fixed rate EUR 4.30 / USD 4.00) — not total cost, no inflation adjustment.
- Macro data (GDP, convergence) kept SEPARATE — context, not proof.
- English text is machine-translated from the Polish source and machine-verified; the Polish record is authoritative.
