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 23HN0056 and 23HN0114 have near-identical descriptions about 188 m apart (funding year 2023; ₱48.98M, ₱96.40M). Worth checking whether they cover the same works. These may be sequential phases of a larger project, with one phase not explicitly labeled.

The only distinguishing marker is 'Phase II' in the second title, while the first title has no phase marker. 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 very close (188m), the titles are otherwise identical, and both are in the same funding year and municipality. Innocent explanation is plausible (sequential phases), but the pattern is worth public attention.
