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 24HL0013 and 23HL0005 have near-identical descriptions about 211 m apart (funding years 2023, 2024; ₱45.08M, ₱44.10M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the previous year's work, but this is not labeled in the titles.
