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 22LG0007 and 23LG0002 have near-identical descriptions about 818 m apart (funding years 2022, 2023; ₱29.40M, ₱49.00M). Worth checking whether they cover the same works. This may be a continuation or expansion of the same flood mitigation project funded in consecutive years.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same river and section, with only 'Barangay' present in one title and not the other. There are no phase, package, or section markers that distinguish them as separate works. The locations are about 818 meters apart, which is within the same barangay/section and could plausibly be a continuation or expansion, but the lack of a phase or package marker in one title makes this a textbook 'unlabelled twin' case per the rule. The evidence is complete and checkable.
