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 24OE0116 and 22OE0030 have near-identical descriptions about 525 m apart (funding years 2022, 2024; ₱29.09M, ₱49.00M). Worth checking whether they cover the same works. The second contract may be a continuation or a new phase of the same drainage system project.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 3' in the first title, while the second title has no phase or package marker. According to the rule guidance, if one title has a phase/package marker and the other has none, this should be published as a possible unlabelled twin or continuation. The locations are close (525 m apart), and the titles are otherwise near-identical, both referring to the same zones in Manila City. The evidence is complete and checkable.
