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 23BG0075 and 22BG0005 have near-identical descriptions about 433 m apart (funding years 2022, 2023; ₱52.83M, ₱44.08M). Worth checking whether they cover the same works. These may be sequential or adjacent phases of a larger flood control project funded in different years.

The titles are near-identical, with only 'Barangay' vs 'Brgy.' as a difference, which is a spelling variant and not a distinguishing marker. Both projects are in the same barangay and municipality, and are about 433 meters apart, which is above the 100m threshold but still close enough to warrant public attention, especially since the works are not clearly labeled as different phases or segments. The evidence is complete and the public can check the records.
