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 22A00010 and 23A00188 have near-identical descriptions about 584 m apart (funding years 2022, 2023; ₱101.33M, ₱91.67M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first phase, or covers a nearby section of the same river.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for 'Brgy.' vs 'Barangay', which is a spelling variant and not a distinguishing marker. Both projects are in the same barangay, same river, same phase, and funded in consecutive years, with the same contractor. The locations are only 584 meters apart, which is within the range for possible duplicate or overlapping works. There are no distinguishing markers or different place names.
