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 22IA0016 and 23IA0017 have near-identical descriptions about 295 m apart (funding years 2022, 2023; ₱39.16M, ₱24.48M). Worth checking whether they cover the same works. This may be a continuation or next phase of the same flood control project, with the earlier contract not specifying the phase.

The only distinguishing marker is 'Phase V' in the second title, while the first title has no phase marker at all. 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. The locations are close (295 m), the titles are otherwise near-identical, and the funding years are consecutive. Innocent explanation is plausible (a continuation or phased implementation), but the pattern is worth public attention.
