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 22AI0066 and 22AI0058 have near-identical descriptions about 539 m apart (funding year 2022; ₱29.16M, ₱48.96M). Worth checking whether they cover the same works. These could be adjacent or sequential segments of flood control works along the same river, with one title specifying a sitio or area within the barangay.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same river and barangay, with only minor wording differences ('Diket - Don Justo Abalos' vs 'Barangay Don Justo Abalos'). There are no phase, package, or section markers, and the only unique word is 'Diket' in the first title, which could be a sitio or area within the barangay, but not a clear distinguishing marker. The projects are funded in the same year, are both for flood control structures along the same river, and are only 539 meters apart. This fits the rule's criteria for a potentially overlapping or duplicate project. Innocent explanations (such as adjacent segments or a continuation not labeled as such) are plausible but do not block publication.
