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 22DJ0049 and 22DJ0001 have near-identical descriptions about 397 m apart (funding year 2022; ₱39.20M, ₱77.20M). Worth checking whether they cover the same works. It is possible these are two segments of a larger project that were bid out separately.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only 'Barangay' vs 'Brgy.' as a difference, which is not a distinguishing marker. Both projects are in the same municipality, funded in the same year, and are less than 400 meters apart. There are no phase, package, or section markers, nor different place names. The evidence is complete and meets the rule's criteria for a plausible duplicate or overlapping scope.
