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 24N00126 and 24N00121 have near-identical descriptions about 68 m apart (funding year 2024; ₱99.00M, ₱48.25M). Worth checking whether they cover the same works. These could be separate segments or phases of shore protection works that were not clearly labeled as such.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same barangay and municipality, with only minor wording differences ('along' vs 'Brgy.'). There are no phase, package, section, or other distinguishing markers, and both are in the same funding year and within 68 meters. This fits the rule's criteria for a potentially overlapping or duplicate project. Innocent explanations (e.g., continuation or expansion of works, or separate segments not clearly labeled) are plausible but do not block publication.
