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 24GI0020 and 22GI0017 have near-identical descriptions about 285 m apart (funding years 2022, 2024; ₱86.85M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers an adjacent stretch not clearly labeled as a separate phase.

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 referring to the construction of the Aganan Flood Control Structure at (Brgy./Barangay) Poblacion, Alimodian, Iloilo, with only minor wording differences ('Barangay' vs 'Brgy.' and an added directional note 'going to Subana'). There are no phase, package, section, or other distinguishing markers, and both are by the same contractor, funded two years apart, and located only 285 meters apart. The only difference is the mention of 'going to Subana' in one title, which does not clearly indicate a distinct segment or phase. This fits the rule's guidance for publishing as a possible duplicate or overlapping project.
