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 24HE0059 and 23HE0133 have near-identical descriptions about 136 m apart (funding years 2023, 2024; ₱96.45M, ₱34.29M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project.
