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 22PA0126 and 22PA0127 have near-identical descriptions about 225 m apart (funding year 2022; ₱49.50M, ₱49.50M). Worth checking whether they cover the same works. It is possible that these are consecutive phases of a larger project, with one phase simply not labeled as such.

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 or package marker. Per rule guidance, if one title has a phase/package marker and the other does not, this is a classic 'unlabelled twin' case and should be published. Both projects are in the same barangay, have the same contractor, same funding year, and are only 225 meters apart, with near-identical titles otherwise.
