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 23DI0017 and 23D00067 have near-identical descriptions about 1790 m apart (funding year 2023; ₱72.35M, ₱154.40M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, but the first was not labeled as a specific phase.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase2' in the second title, while the first title has no phase 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. Both projects are in the same barangay, same year, and have highly similar titles, with no other distinguishing place or structure markers.
