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 22AB0087 and 22AB0085 have near-identical descriptions about 56 m apart (funding year 2022; ₱49.00M, ₱49.00M). Worth checking whether they cover the same works. One project may cover a specific section (right bank, Sitio Sinigpit 2) while the other covers a broader or adjacent area.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical and refer to the same creek and barangay, with only one title specifying 'Right Bank' and 'Sitio Sinigpit 2' while the other omits these details. The absence of a phase/package/lot marker in either title means this could plausibly be the same or overlapping works, or a continuation that is not clearly labelled. The distance between the coordinates (56 meters) is small enough that the works could overlap or be adjacent. The distinguishing markers ('Right Bank', 'Sitio Sinigpit 2') are only present in one title, not both, so per the rule, this is a case for publishing as a possible unlabelled twin or overlapping project.
