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 22EF0008 and 23EF0075 have near-identical descriptions about 3 m apart (funding years 2022, 2023; ₱29.40M, ₱19.55M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the first project.

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 'Municipality of' in the second title, which is not a distinguishing marker per the rule. Both projects are at nearly the same coordinates (3 meters apart), in the same barangay and municipality, and funded in consecutive years. There are no phase, package, or section markers, nor different place names. This fits the criteria for a potentially duplicate or overlapping project worth public attention.
