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 22BH0109 and 22BH0123 have near-identical descriptions about 521 m apart (funding year 2022; ₱96.50M, ₱14.83M). Worth checking whether they cover the same works. These may be separate segments or components of flood control works within the same barangay.

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 'Construction of Flood Control [Structure/System]' at Barangay Carabatan Chica, Cauayan City, Isabela, with only minor wording differences ('Structure' vs 'System', 'Brgy.' vs 'Barangay', and the presence of 'at'). There are no distinguishing markers such as phase, package, section, or different locations. Both projects are in the same barangay, funded in the same year, and are only 521 meters apart. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations (such as different scopes or segments within the same barangay) are possible but do not block publication.
