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 24FJ0023 and 22FJ0028 have near-identical descriptions about 239 m apart (funding years 2022, 2024; ₱48.96M, ₱35.25M). 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 different segment of the same river.

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 minor wording differences (Barangay vs Brgy, 'at' vs comma), and both refer to the same river and barangay in the same municipality. There are no distinguishing markers such as phase, package, or section numbers, nor do the titles mention different sites or structures. The projects are about 239 meters apart and funded in different years, which fits the rule's intent to flag possible duplicate or overlapping works. All necessary records and URLs are present.
