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 23GB0036 and 24GB0084 have near-identical descriptions about 352 m apart (funding years 2023, 2024; ₱14.70M, ₱49.50M). 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 but distinct section of the river.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, with the only difference being the mention of 'Barangay Poblacion' in the first title. Both are for flood control structures along the same river in the same municipality, funded in consecutive years, and are only 352 meters apart. The absence of phase, package, or section markers and the high title similarity suggest a possible overlap or continuation that is not clearly labelled. The difference in barangay mention is not a strong enough distinguishing marker, as the second title could simply be less specific.
