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 23IE0019 and 23IE0036 have near-identical descriptions about 894 m apart (funding year 2023; ₱48.26M, ₱4.81M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or additional phase of the first project.

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase or package marker. According to the rule-specific guidance, if one title has a phase/package marker and the other does not, this should be published as a possible unlabelled twin or continuation. Both projects are in the same barangay, funded in the same year, and are less than 1 km apart, with highly similar titles.
