Indicator C3 — Duplicate or Near-Duplicate Projects

AI-verified / Na-verify ng AI Data as of October 21, 2026

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contracts 23K00185 and 23KL0072 have near-identical descriptions about 460 m apart (funding year 2023; ₱129.00M, ₱4.95M). Worth checking whether they cover the same works. One project may be a smaller component or preparatory work for the larger project, or they may cover adjacent but not overlapping sections.

How this was checked

publish · confidence 0.92

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with no distinguishing markers or place names that would indicate different works. Both projects are in the same municipality, same river, same downstream location, and funded in the same year. The only difference is a minor preposition ('at'), which is not a distinguishing marker. The distance between the coordinates (460 m) is above the 100 m threshold, but the titles' overlap and lack of distinguishing markers make this worth publishing as a potential duplicate or overlapping project indicator.
