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 24BB0083 and 23BB0085 have near-identical descriptions about 3282 m apart (funding years 2023, 2024; ₱48.24M, ₱48.99M). Worth checking whether they cover the same works. It is possible that these are sequential or adjacent flood control projects in the same area funded in different years.

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 only the word 'at' differing, and both refer to 'Flood Control' at 'Asassi, Baggao, Cagayan'. There are no distinguishing markers such as phase, package, section, or different place names. The projects are about 3.3 km apart, which is outside the 100 m threshold for identical-location flags, but the rule covers near-duplicates within the same municipality. The evidence is complete and the public can check the records.
