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 23PA0047 and 22PA0108 have near-identical descriptions about 37 m apart (funding years 2022, 2023; ₱144.75M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, with the only difference being the word 'Structure' in one title. There are no phase, package, section, or place markers distinguishing them, and both are at nearly the same coordinates (37 m apart) in the same municipality, funded in consecutive years, and by the same contractor. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations are possible, but the evidence is sufficient and clear for public review.
