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 23HO0144 and 23HO0163 have near-identical descriptions about 85 m apart (funding year 2023; ₱96.21M, ₱96.40M). Worth checking whether they cover the same works. It is possible these are two segments of the same riverbank, each described with a different barangay as the starting point.

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 no distinguishing markers or unique place names in either title that would indicate they are different works. Both are for 'Construction of Revetment Wall' at the same two barangays, just with the order of the barangay names swapped. The projects are funded in the same year, by the same contractor, and are only 85 meters apart. This fits the rule's criteria for a potentially duplicate or overlapping project. The evidence is complete and checkable.
