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 22LA0049 and 23LI0029 have near-identical descriptions about 547 m apart (funding years 2022, 2023; ₱67.55M, ₱77.20M). 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 stretch of the river.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with the only difference being the presence of 'Brgy.' in one title, which is not a distinguishing marker per the rule. Both projects are for the construction of a revetment at the same bridge and river, in the same barangay and municipality, but funded in consecutive years and about 547 meters apart. There are no phase, package, section, or other location markers that would indicate these are distinct works. The evidence is complete and the public can verify the records.
