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 22FC0073 and 23FC0039 have near-identical descriptions about 769 m apart (funding years 2022, 2023; ₱24.50M, ₱95.55M). Worth checking whether they cover the same works. It is possible that the second project is an extension or a different segment along the river within the same barangay.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical and refer to the same barangay (Mabilo II, Labo, Camarines Norte), with one title specifying 'Labo River' and the other only 'Barangay'. There are no phase, package, section, or station markers, and the only difference is the mention of 'river' in one title. The locations are 769 meters apart, which is within the same barangay and could plausibly refer to the same or overlapping works. The evidence is complete and meets the rule's requirements.
