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 22FE0041 and 24FE0021 have near-identical descriptions about 387 m apart (funding years 2022, 2024; ₱47.98M, ₱133.17M). Worth checking whether they cover the same works. This may be a continuation or expansion of the same dike project funded in a later year.

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 spelling/formatting differences (Brgy. vs Barangay, hyphenation), and both refer to the same location (Del Carmen-Del Rosario, Minalabac, Camarines Sur) and the same type of work (dike construction along Bicol River). The projects are about 387 meters apart, which is outside the strict 100m threshold but still close enough to warrant public attention, especially given the high title similarity (0.972) and lack of distinguishing markers. Innocent explanations such as a continuation or expansion of the same project in a later year are plausible, but the indicator is valid and worth publishing.
