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 22AI0061 and 22AI0066 have near-identical descriptions about 1378 m apart (funding year 2022; ₱29.37M, ₱29.16M). Worth checking whether they cover the same works. The two contracts may cover adjacent or extended sections of the river, with 'Diket' indicating an additional area included in one project.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same river and barangay, with only 'Diket' added in the second title. There are no phase, package, or section markers, and both projects are in the same municipality, funded in the same year, by the same contractor, and are about 1.4 km apart. The only distinguishing word is 'Diket', which appears to be an additional place or sitio, but the rest of the title overlaps and the works could plausibly cover overlapping or adjacent sections. This fits the guidance for publishing when one title is the other plus an extra place, as the overlap is significant and could indicate possible double funding or unclear project boundaries.
