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 23IE0010 and 22IE0062 have near-identical descriptions about 988 m apart (funding years 2022, 2023; ₱48.02M, ₱48.75M). 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 a different segment not specified in the title.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only 'Barangay' vs 'Brgy' as a difference, which is a spelling variant and not a distinguishing marker. Both projects are in the same barangay and municipality, funded in consecutive years, by the same contractor, and are less than 1 km apart. There are no phase, package, or section markers, nor different place names. This fits the rule's publish criteria for possible duplicate or overlapping works.
