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 24MF0022 and 24MF0017 have near-identical descriptions about 135 m apart (funding year 2024; ₱45.23M, ₱44.94M). Worth checking whether they cover the same works. It is possible these are two segments of the same flood control structure, described with the endpoints in different orders.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both project titles are near-identical, with only the order of 'Kolambog - Bambad' vs 'Bambad - Kolambog' differing, and no distinguishing markers or place names unique to either. Both are in the same municipality, funded in the same year, and are only 135 meters apart. This fits the rule's publish criteria for potentially overlapping or duplicate works.
