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 23AD0069 and 23AD0074 have near-identical descriptions about 85 m apart (funding year 2023; ₱9.60M, ₱9.89M). Worth checking whether they cover the same works. It is possible these are two separate but adjacent flood control structures 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, both refer to 'Flood Control' in Brgy. Ambugat, Burgos, Ilocos Sur, and are only 85 meters apart. There are no distinguishing markers (such as phase, package, section, or different sitios/barangays) in either title. Both are funded in the same year, but have different contractors. This fits the C3 rule for potentially overlapping or duplicate works.
