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 23FE0014 and 23FE0056 have near-identical descriptions about 86 m apart (funding year 2023; ₱67.46M, ₱72.37M). Worth checking whether they cover the same works. One contract may be for a specific revetment structure, while the other covers broader flood control works in the same area.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both project titles refer to construction along the same river and barangay, with only minor wording differences ('revetment' vs 'flood control', 'Barangay' vs 'Brgy.'). There are no phase, package, section, or site markers distinguishing them, and both are in the same funding year and location, about 86 meters apart. This fits the rule's criteria for a potentially overlapping or duplicate project. Innocent explanation is plausible (e.g., one contract may be for a specific structure type, the other for a broader flood control intervention), but the overlap is significant enough to warrant public attention.
