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 23OF0086 and 22OF0031 have near-identical descriptions about 1607 m apart (funding years 2022, 2023; ₱48.99M, ₱14.47M). Worth checking whether they cover the same works. This may simply be a continuation or second phase of the same flood control project.

Prompt: v4.1

The only distinguishing marker is 'Phase 2' in one title, with the other title unlabelled. Per rule guidance, this is a classic 'unlabelled twin' case and should be published. The locations are in the same barangay and the titles are otherwise identical, with high similarity. Innocent explanation is plausible (e.g., a continuation or expansion of the same project), but the pattern is worth public attention.
