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 22NG0054 and 22NG0014 have near-identical descriptions about 261 m apart (funding year 2022; ₱48.50M, ₱96.50M). Worth checking whether they cover the same works. It is possible these are two phases or segments of a larger project that were not labeled as such in the titles.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, differing only in the spelling variant 'Brgy.' vs 'Barangay', which is not a distinguishing marker per the rule. Both are for 'Construction of Flood Mitigation Structure along Surigao River, [Brgy./Barangay] Quezon, Surigao City, Surigao del Norte', funded in the same year, and are only 261 meters apart. There are no phase, package, section, or other location markers that would distinguish them as separate works. The evidence is complete and checkable.
