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 22DQ0024 and 23DQ0007 have near-identical descriptions about 45 m apart (funding years 2022, 2023; ₱4.95M, ₱4.95M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project.

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical with no distinguishing markers or extra place names, and are only 45 meters apart. The only difference is a comma, which is not a distinguishing marker. The funding years are consecutive, which could indicate a continuation or repeat funding for the same or overlapping works. All required records and fields are present.
