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 23FG0039 and 22FG0010 have near-identical descriptions about 112 m apart (funding years 2022, 2023; ₱95.54M, ₱19.60M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or second phase of the first project, but the earlier project was not labeled as such.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the first title, while the second title has no phase or package marker. According to the rule guidance, if one title has a phase/package marker and the other does not, this should be published as a possible unlabelled twin or continuation. The locations are very close (112 m), and the rest of the title is identical, with no other distinguishing place or structure markers.
