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 22OB0161 and 22OB0156 have near-identical descriptions about 531 m apart (funding year 2022; ₱91.64M, ₱59.57M). Worth checking whether they cover the same works. One project may be a continuation or expansion of the other, but the second contract does not specify a phase.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase II' in the first title, while the second title has no phase or package marker at all. Per rule guidance, if one title has a phase/package marker and the other has none, this is a classic 'unlabelled twin' case and should be published. The locations are close (531m), the titles are otherwise near-identical, and both are in the same municipality and year. The evidence is complete.
