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 24BC0077 and 22BC0082 have near-identical descriptions about 316 m apart (funding years 2022, 2024; ₱24.50M, ₱43.12M). 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 section of the same flood control system.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to 'Lucban Flood Control along Abulug River' in Abulug, Cagayan, and are only 316 meters apart. The only difference in the titles is the addition of the word 'Structure' and the mention of 'Lucban' in the second title's location string, which does not constitute a distinguishing marker such as a phase, package, or different sitio/barangay. There are no phase/package/section/side markers or different place names that would indicate these are distinct works. The evidence is complete and meets the rule's criteria for publishing.
