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 23OD0222 and 22OD0110 have near-identical descriptions about 24 m apart (funding years 2022, 2023; ₱19.13M, ₱9.55M). Worth checking whether they cover the same works. The second contract may simply be a continuation or next phase of the same project, but the earlier one was not labeled as such.

How this was checked

publish · confidence 0.80

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. According to the rule-specific guidance, if one title has a phase/package marker and the other has none, this should be published as a possible unlabelled twin. The locations are only 24 meters apart, the titles are otherwise near-identical, and both are in the same barangay and road. The evidence is complete and checkable.
