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 22MH0022 and 23MH0016 have near-identical descriptions about 2121 m apart (funding years 2022, 2023; ₱67.55M, ₱49.00M). Worth checking whether they cover the same works. It is possible that these are two phases or extensions of river bank protection works in the same barangay, funded in different years.

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 by 'Brgy.' vs 'Barangay', which is a spelling variant and not a distinguishing marker. Both are for 'Construction of River Bank Protection' at the same barangay, in the same municipality, but funded in consecutive years and about 2.1 km apart. There are no phase, package, section, or other location markers that would indicate these are distinct works. The evidence is complete and meets the rule's criteria for a plausible duplicate or overlapping project.
