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 23FE0056 and 23FE0014 have near-identical descriptions about 86 m apart (funding year 2023; ₱72.37M, ₱67.46M). Worth checking whether they cover the same works. It is possible that the two contracts cover different types of structures or segments along the same river.

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 construction along the same river and barangay, and are funded in the same year, with locations only 86 meters apart. The only differences in the titles are 'Flood Control' vs 'Revetment' and 'Brgy.' vs 'Barangay', which are not distinguishing markers per the rule. There is no phase, package, or section marker, nor a different site name. This fits the criteria for a potentially overlapping or duplicate project worth public attention.
