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 22AH0071 and 22AH0126 have near-identical descriptions about 323 m apart (funding year 2022; ₱14.70M, ₱24.01M). Worth checking whether they cover the same works. It is possible these are two segments of riverbank protection works in the same barangay that were procured separately but not labeled as such.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects have exactly the same title with no distinguishing markers, are in the same barangay and municipality, funded in the same year, and are only 323 meters apart. There is no phase, package, or section marker to distinguish them, and the code confirms the titles are identical. This fits the rule's publish criteria for possible duplicate or overlapping works.
