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 23GF0007 and 22GF0047 have near-identical descriptions about 1321 m apart (funding years 2022, 2023; ₱14.55M, ₱9.70M). Worth checking whether they cover the same works. One project may focus on the Nanga area specifically, while the other covers a broader or different stretch of the Guimbal shoreline.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing word is 'Nanga' in the first title, which appears to be a sitio or locality within Guimbal, but the second title is generic ('Guimbal Shoreline Protection') and does not specify a different sitio, barangay, or section. The projects are about 1.3 km apart, which is not so far as to clearly indicate different works, especially for shoreline protection. There is no phase, package, or section marker. Innocent explanation is plausible (e.g., one project is for Nanga specifically, the other for a broader or different stretch), but the overlap and lack of clear distinction make this worth publishing.
