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 22IA0054 and 22IA0055 have near-identical descriptions about 22 m apart (funding year 2022; ₱28.48M, ₱14.17M). Worth checking whether they cover the same works. It is possible that these are sequential phases of a larger project, but the first contract does not specify its phase.

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase marker. 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 locations are only 22 meters apart, and both are in the same municipality, with the same contractor and funding year. There is enough information for public checking.
