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 22BG0081 and 23BG0038 have near-identical descriptions about 479 m apart (funding years 2022, 2023; ₱43.17M, ₱43.44M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a nearby section not specified in the titles.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for 'Brgy.' vs 'Barangay', which is a spelling variant and not a distinguishing marker. Both projects are in the same barangay and municipality, with similar descriptions and funding in consecutive years. The distance is 479 meters, which is above the 100m threshold, but the rule is for near-duplicate titles within the same municipality, and the code has already flagged this as a potential overlap. There are no distinguishing markers or different sites named.
