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 22DL0145 and 23DL0041 have near-identical descriptions about 214 m apart (funding years 2022, 2023; ₱29.40M, ₱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, or covers a nearby stretch of the same river.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have near-identical titles with no distinguishing markers, are located only 214 meters apart, and are funded in consecutive years. There are no phase, package, section, or place name differences in the titles. 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.
