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 22GK0172 and 24GK0075 have near-identical descriptions about 926 m apart (funding years 2022, 2024; ₱29.40M, ₱4.95M). Worth checking whether they cover the same works. The second project may be a smaller, more localized follow-up or extension in a specific barangay.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except that the second specifies 'Barangay Batea' while the first is generic to the municipality. There are no phase/package/section markers or other distinguishing markers. The distance is 926m, which is above the 100m threshold, but the rule is for near-duplicate titles within the same municipality, not just at the same spot. The evidence is complete and the public can check the records. Innocent explanation: the second project may be a smaller, more localized follow-up or extension in a specific barangay.
