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 23GG0074 and 24GG0015 have near-identical descriptions about 25 m apart (funding years 2023, 2024; ₱19.49M, ₱48.89M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a different type of structure at the same site.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same river and municipality, with only minor wording differences ('Slope Protection' vs 'Structure'). There are no phase, package, station, or barangay markers distinguishing them, and the locations are only 25 meters apart. The only difference is the inclusion of 'Slope Protection' in one title, which is not a clear distinguishing marker per the rule. Innocent explanations (e.g., continuation or expansion of works) are plausible but do not block publishing.
