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 22PA0193 and 22PA0362 have near-identical descriptions about 507 m apart (funding year 2022; ₱96.50M, ₱95.56M). Worth checking whether they cover the same works. It is possible these are two phases or segments of a larger flood control project that were not clearly labeled as such.

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, both refer to 'Flood Control Structure' in Barangay Cardona, Dolores, Abra, with no distinguishing markers or different place names. The only difference is a minor word order change, which does not indicate different works. Both are funded in 2022, are about 507 meters apart, and have similar scopes and costs. The evidence is complete and meets the rule's criteria for a plausible duplicate or overlapping project.
