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 23HL0066 and 23HL0053 have near-identical descriptions about 96 m apart (funding year 2023; ₱49.00M, ₱49.00M). Worth checking whether they cover the same works. These may be two phases or segments of a larger river control project, with one contract not explicitly labeled as a phase.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase II' in the first title, while the second title has 'Upstream A' but no explicit phase or package marker. According to the rule, if one title has a phase/package marker and the other does not, this should be published as a possible unlabelled twin. The locations are very close (96 m), the titles are highly similar, and both are in the same funding year with the same contractor and cost. Innocent explanations are possible, but the pattern is genuinely unusual and worth public attention.
