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 22IA0025 and 23IA0021 have near-identical descriptions about 265 m apart (funding years 2022, 2023; ₱29.40M, ₱29.39M). Worth checking whether they cover the same works. This may simply reflect a continuation of the same flood control project in a new 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, this is a classic 'unlabelled twin' case and should be published. The locations are close (265 m), the titles are otherwise near-identical, and both are in the same municipality with the same contractor. Innocent explanation is plausible (sequential phases), but the pattern is worth public attention.
