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 24OG0021 and 23OG0072 have near-identical descriptions about 54 m apart (funding years 2023, 2024; ₱49.00M, ₱9.76M). Worth checking whether they cover the same works. It is possible that the second contract covers Phase 1 and the first contract is a continuation (Phase 2) of the same project.
