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 22CC0308 and 22CC0316 have near-identical descriptions about 525 m apart (funding year 2022; ₱49.00M, ₱47.52M). Worth checking whether they cover the same works. These may be adjacent or contiguous sections of flood control works awarded as separate contracts.

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 minor wording differences (Barangay vs Brgy, 'and' vs '&'), and both refer to the same set of locations (Virgen Delos Flores, Sta. Barbara, Tiaong, Baliuag, Bulacan). There are no distinguishing markers such as different phases, packages, or additional/different place names. Both projects are in the same funding year, municipality, and are only 525 meters apart. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations are possible, such as the projects covering adjacent or contiguous stretches, but the evidence is sufficient and clear for public review.
