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 24CE0195 and 23CE0185 have near-identical descriptions about 149 m apart (funding years 2023, 2024; ₱4.90M, ₱4.90M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or that additional structures were needed in the same area.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for the singular/plural 'structure/structures', which is not a distinguishing marker per the rules. Both projects are at the same river and barangay, funded in consecutive years, and are only 149 meters apart. There are no phase, package, section, or site markers that would distinguish them as separate works. The evidence is complete and meets the rule's criteria for publishing.
