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 22FH0017 and 22FH0067 have near-identical descriptions about 23 m apart (funding year 2022; ₱29.40M, ₱29.40M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the first project, but the first was not labeled as a phase.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase marker. Per rule guidance, if one title has a phase marker and the other does not, this is a classic 'unlabelled twin' scenario and should be published. The locations are only 23 meters apart, and both are in the same barangay and municipality, with near-identical titles and funding years. The evidence is complete and checkable.
