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 22II0017 and 24II0038 have near-identical descriptions about 305 m apart (funding years 2022, 2024; ₱77.20M, ₱48.97M). 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 the drainage system was a separate component.

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 'and Drainage System' in the first title. There are no phase, package, section, or place markers distinguishing them, and both are located in the same river basin and municipality, about 305 meters apart. This fits the guidance for publishing: the works may overlap or be continuations, and the evidence is complete with record IDs and URLs.
