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 23EH0082 and 24EH0114 have near-identical descriptions about 73 m apart (funding years 2023, 2024; ₱48.99M, ₱48.25M). Worth checking whether they cover the same works. It is possible that the second contract is a planned continuation or expansion 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. Per the rule-specific guidance, if one title has a phase/package marker and the other does not, this is a classic 'unlabelled twin' scenario and should be published. The packet provides all necessary record IDs, URLs, and figures for public checking.
