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 24BC0065 and 24BC0072 have near-identical descriptions about 1455 m apart (funding year 2024; ₱48.23M, ₱48.41M). Worth checking whether they cover the same works. It is possible that the unlabelled contract covers a different section or is a continuation that was not explicitly marked as a package.

The only distinguishing marker is 'Package 1' in the second title, while the first title has no such marker. Per rule guidance, if one title has a package/phase marker and the other does not, this is a classic 'unlabelled twin' case and should be published. The locations are about 1.5 km apart, but both are in the same municipality and the titles otherwise overlap almost exactly.
