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 23GG0111 and 22GG0093 have near-identical descriptions about 7576 m apart (funding years 2022, 2023; ₱48.51M, ₱43.22M). Worth checking whether they cover the same works. These may be separate segments of flood control along the same river, funded in different years.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are completely identical with no distinguishing markers or place names that would indicate different works, and the projects are in the same municipality but 7.5 km apart. This fits the rule's intent: possible duplicate or overlapping works at different spots along the same river. Innocent explanations (e.g., separate segments of the river) are plausible but do not block publishing.
