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 22BB0023 and 23BB0065 have near-identical descriptions about 60 m apart (funding years 2022, 2023; ₱24.50M, ₱48.98M). 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 part of the same river.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both at Dalla, Baggao, Cagayan, with no distinguishing phase, package, or section markers. The only differences are 'River' vs 'Flood' and the addition of 'Structure' in the second title, which are not distinguishing markers per the rules. The projects are about 60 meters apart and funded in consecutive years, which fits the pattern for possible duplicate or overlapping works. All required record details are present.
