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 24OG0092 and 23OG0047 have near-identical descriptions about 209 m apart (funding years 2023, 2024; ₱20.25M, ₱9.80M). Worth checking whether they cover the same works. The two contracts may cover different phases of a larger project along the same creek.

The only distinguishing marker is 'Phase II' in the second title, while the first title has no phase marker. Per rule guidance, if one title has a phase marker and the other does not, this is a classic 'unlabelled twin' scenario and should be published. The packet provides all necessary details, including contract IDs, URLs, and coordinates.
