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 24HI0001 and 23HI0002 have near-identical descriptions about 1586 m apart (funding years 2023, 2024; ₱71.63M, ₱48.99M). Worth checking whether they cover the same works. The two projects may represent different phases or sections of flood control works along the same river, with one specifically labeled as 'Upstream' and the other possibly covering a different or broader area.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Upstream' in the 2024 project title, while the 2023 project title does not specify a section. According to the rule, if one title has a section marker and the other does not, this is considered a potential unlabelled twin and should be published. The locations are about 1.6 km apart, which is plausible for either a continuation or a possible overlap. The evidence is complete and the public can check the records.
