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 22GN0001 and 23GN0051 have near-identical descriptions about 743 m apart (funding years 2022, 2023; ₱49.00M, ₱80.09M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, but this is not labeled in the titles.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have identical titles with no distinguishing markers (no phase, package, section, or different place names), are in the same municipality, and are only 743 meters apart. The only difference is the funding year. This fits the rule's criteria for a potentially duplicate or overlapping project. All necessary records and URLs are present for public checking.
