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 22GG0088 and 24GG0054 have near-identical descriptions about 988 m apart (funding years 2022, 2024; ₱34.30M, ₱34.30M). Worth checking whether they cover the same works. This may be a continuation or expansion of flood control works along the same river.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with only the word 'Structure' present in the first title and no distinguishing markers such as phase, package, section, or different place names. Both projects are in the same municipality, funded two years apart, and are less than 1 km apart. The evidence is complete and meets the rule's criteria for a plausible duplicate or overlapping scope. Innocent explanations (such as a continuation or expansion of works) are possible but do not block publication.
