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 project is a continuation or expansion of the first, or addresses a different segment not specified in the title.

The two project titles are near-identical, differing only by the word 'at', and both refer to 'San Miguel, Baggao, Cagayan' with no distinguishing markers such as phase, package, or section. The projects are only 3 meters apart and funded in consecutive years, which fits the rule's criteria for a potentially duplicate or overlapping project. All necessary records and fields are present.
