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 22OI0015 and 22OI0067 have near-identical descriptions about 714 m apart (funding year 2022; ₱67.45M, ₱29.35M). Worth checking whether they cover the same works. It is possible that these are two phases or segments of slope protection works along the same creek, with one contract specifying the barangay and the other covering a broader or adjacent area.

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 that one specifies 'Brgy. Talon 5' while the other does not. According to the rule, if one title has a barangay marker and the other does not, this is considered a potential unlabelled twin and should be published. Both projects are in the same municipality, funded in the same year, by the same contractor, and are only 714 meters apart. There are no distinguishing markers that would indicate they are clearly different works.
