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 22CE0043 and 24CE0100 have near-identical descriptions about 894 m apart (funding years 2022, 2024; ₱91.67M, ₱47.77M). 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 a different segment of the same river in the same barangay.

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 except for 'Brgy.' vs 'Barangay', which is a spelling variant and not a distinguishing marker. Both are for flood control structures along the same river and barangay, funded in different years, and are less than 1 km apart. There are no phase, package, section, or other location markers that would distinguish them as separate works. The evidence is complete and meets the rule's criteria for a plausible duplicate or continuation.
