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 22GB0014 and 23GB0023 have near-identical descriptions about 790 m apart (funding years 2022, 2023; ₱8.26M, ₱57.90M). 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 in the same barangay.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are completely identical with no distinguishing markers or place names that would indicate different works. The projects are in the same barangay and municipality, and the only differences are the funding years and locations about 790 meters apart. This fits the rule's publish criteria for near-identical titles at the same spot funded in different years, with no phase/package/section markers to distinguish them.
