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 24FN0008 and 23FN0051 have near-identical descriptions about 254 m apart (funding years 2023, 2024; ₱96.50M, ₱98.93M). 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 nearby stretch of the same river.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with only 'Barangay' vs 'Brgy.' as a difference, which is a spelling variant and not a distinguishing marker. Both are for flood mitigation structures along Barit River in Antipolo Old Section, Nabua, Camarines Sur, funded in consecutive years and located only 254 meters apart. There are no phase, package, section, or site markers that would indicate these are distinct works. The evidence is complete and meets the rule's criteria.
