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 22AE0023 and 23AE0012 have near-identical descriptions about 417 m apart (funding years 2022, 2023; ₱48.02M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers additional repairs not included in the initial contract.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with the only difference being 'Brgy.' vs 'barangay', which is a spelling variant and not a distinguishing marker. Both projects are in the same barangay, municipality, and refer to the same river control structure, funded in consecutive years, and are about 417 meters apart. There are no phase, package, section, or other location markers that would distinguish them as separate works. The evidence is complete and meets the rule's criteria for publishing.
