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 24BB0088 and 23BB0021 have near-identical descriptions about 3 m apart (funding years 2023, 2024; ₱48.23M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with only the word 'at' differing, and both refer to the same location (San Miguel, Baggao, Cagayan) with coordinates just 3 meters apart. There are no distinguishing markers such as phase, package, section, or different place names. The funding years are consecutive, which could indicate either a continuation or possible double funding for the same works. The evidence is complete and meets the rule's criteria for publishing.
