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 22BG0021 and 23BG0091 have near-identical descriptions about 833 m apart (funding years 2022, 2023; ₱43.46M, ₱52.70M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a nearby but distinct section.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both refer to 'Cagayan River Flood Control Project' at (Brgy./Barangay) Labinab Pequeño/Pequeno, Reina Mercedes, Isabela. The only differences are spelling variants and the use of 'Brgy.' vs 'Barangay', which are not distinguishing markers per the rule. The projects are about 833 meters apart and funded in consecutive years, with different contractors. There are no phase, package, section, or other markers to distinguish them as separate works. Innocent explanations are possible (e.g., continuation or expansion), but the pattern meets the criteria for publishing.
