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 23IA0022 and 22IA0054 have near-identical descriptions about 191 m apart (funding years 2022, 2023; ₱18.96M, ₱28.48M). 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 labeled by phase.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase III' in the 2023 project title, while the 2022 project has no phase or package marker. 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 very close (191 m), the titles are otherwise near-identical, and both are in the same municipality. Innocent explanation is plausible (continuation or phased implementation), but the pattern is worth public attention.
