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 23AJ0061 and 23AJ0006 have near-identical descriptions about 588 m apart (funding year 2023; ₱4.85M, ₱19.19M). Worth checking whether they cover the same works. One project may be a continuation or additional phase of the other, but the first title does not specify a phase.

The only distinguishing marker is 'Phase III' in the second title, while the first title has no phase marker at all. 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 locations are close (588 m), the titles are otherwise identical, and both are in the same barangay and river. Innocent explanation is plausible but does not block publishing.
