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 22DF0009 and 23DF0090 have near-identical descriptions about 481 m apart (funding years 2022, 2023; ₱90.71M, ₱91.67M). Worth checking whether they cover the same works. The second project may simply be a continuation or expansion of the first.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase II' in the second title, while the first title has no phase marker at all. Per guidance, if one title has a phase marker and the other does not, this is considered a potential unlabelled twin and should be published. The locations are close (481 m), titles are highly similar, and both are for revetment along the same river and barangay section. Innocent explanation: the second project may be a continuation or expansion of the first, but the lack of a phase marker in the first title makes it worth flagging.
