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 24FJ0023 and 22FJ0028 have near-identical descriptions about 239 m apart (funding years 2022, 2024; ₱48.96M, ₱35.25M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers a different segment of the same river.

The titles are near-identical, both refer to 'Construction of Flood Control Concrete Revetment' at Gaid River, Barangay/Brgy. Gaid, Dimasalang, Masbate. The only differences are minor wording and spelling variants (Barangay vs Brgy, presence/absence of 'at'), which are not distinguishing markers per the rule. The projects are about 239 meters apart and funded in different years, with no phase/package/section markers to distinguish them. All required records and fields are present.
