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 22AH0135 and 22AH0126 have near-identical descriptions about 588 m apart (funding year 2022; ₱27.44M, ₱24.01M). Worth checking whether they cover the same works. These could be two separate but adjacent protection works along the same riverbank, each covering a different stretch.

How this was checked

publish · confidence 0.92

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, both refer to 'Construction of Riverbank Protection' at the same barangay and municipality, and both are funded in the same year by the same contractor. The only difference in the titles is the word 'Structure' at the end of one, which is not a distinguishing marker per the rules. The locations are about 588 meters apart, which is outside the strict 100m threshold but still close enough to warrant public attention, especially since the titles do not specify different segments, phases, or sites. There are no distinguishing markers such as phase, package, section, or different place names. The evidence is complete and checkable.
