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 23BG0012 and 24BG0093 have near-identical descriptions at the same coordinates (funding years 2023, 2024; ₱24.13M, ₱48.75M). Worth checking whether they cover the same works. It is possible that the first contract covered an earlier phase or a general scope, and the second contract is a clearly labelled continuation (Phase III) of the same project.

The only distinguishing marker is 'Phase III' in the second title, while the first title has no phase marker at all. Per rule guidance, this is a classic 'unlabelled twin' case: the first contract may be an earlier phase or a general/initial project, and the second is explicitly marked as Phase III. Both are at the exact same coordinates, in the same barangay, with near-identical titles and consecutive funding years. This fits the pattern for potential double funding or continuation without clear labelling.
