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 22GG0063 and 23GG0072 have near-identical descriptions about 59 m apart (funding years 2022, 2023; ₱62.36M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first.

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 only the word 'structure' present in the first title and not in the second, and no phase, package, section, or place markers distinguishing them. Both are for flood control/slope protection along the same river in the same municipality, funded in consecutive years, and are only 59 meters apart. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations (such as a continuation or extension of works) are plausible but do not block publication.
