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 24NH0041 and 23N00139 have near-identical descriptions about 167 m apart (funding years 2023, 2024; ₱96.50M, ₱102.28M). Worth checking whether they cover the same works. These may be consecutive phases or extensions of flood protection works at the same bridge.

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 general location (Hubo Bridge, Upstream, Barangay/Brgy. Buhisan, San Agustin, Surigao del Sur) with only minor differences: one mentions 'Abutment B' and the other does not, and the spelling of 'Barangay' vs 'Brgy.' is not a distinguishing marker. The only extra marker is 'Abutment B' in the second title, but the first title could plausibly cover the same or overlapping works, as it does not specify which abutment or if it is more general. The projects are about 167 meters apart, which is close enough for potential overlap, especially for river/bridge works. Both are by the same contractor and in consecutive years. Innocent explanations are possible (e.g., phased or extended works, or different parts of the bridge), but the overlap is significant enough to warrant public attention.
