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. It is possible that the second project is a continuation or next phase of the first, but the first contract did not specify a phase.

Prompt: v4.1

Checked: October 22, 2026

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