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 24AD0074 and 23AD0045 have near-identical descriptions about 375 m apart (funding years 2023, 2024; ₱48.25M, ₱29.40M). 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 an adjacent section of the river.

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 one title, which is not a distinguishing marker per the rule. Both projects are in the same municipality, refer to the same river, and are only 375 meters apart. There are no phase, package, section, or place markers that would indicate they are distinct works. The evidence is complete and meets the rule's criteria for publishing.
