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 22AD0098 and 24AD0076 have near-identical descriptions about 62 m apart (funding years 2022, 2024; ₱14.70M, ₱48.25M). 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 works were needed after the initial construction.

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, with the only difference being the addition of the word 'Structure' in the second title, which is not a distinguishing marker per the rule. Both projects are at nearly the same coordinates (62 meters apart), in the same municipality, and have the same contractor. There are no phase, package, section, or place markers that would distinguish them as separate works. The evidence is complete and meets the rule's criteria for publishing.
