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 22GG0088 and 24GG0054 have near-identical descriptions about 988 m apart (funding years 2022, 2024; ₱34.30M, ₱34.30M). 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 not specified in the title.

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 word 'Structure' in the first title, which is not a distinguishing marker per the rules. Both projects are in the same municipality, funded two years apart, by the same contractor, and are less than 1 km apart. 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.
