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 24NH0041 and 23N00139 have near-identical descriptions about 167 m apart (funding years 2023, 2024; ₱96.50M, ₱102.28M). Worth checking whether they cover the same works. It is possible that the two contracts cover different parts of the bridge or riverbank, such as separate abutments or sections.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to dike revetment works along the Hubo River Basin protecting Hubo Bridge, and are located in the same barangay and municipality. The only additional marker in the second title is 'Abutment ''B''', which could indicate a specific part of the bridge but does not clearly distinguish the overall scope as a separate phase, package, or location. There are no phase/package/section/segment markers or different place names. The projects are about 167 meters apart and funded in consecutive years, with the same contractor. This fits the rule's criteria for a potentially overlapping or duplicate project.
