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 23F00025 and 22F00102 have near-identical descriptions about 60 m apart (funding years 2022, 2023; ₱101.32M, ₱101.33M). Worth checking whether they cover the same works. One project may be a continuation, expansion, or repair of the other.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects are only 60 meters apart, have near-identical titles, and both refer to revetment works along the same river, downstream of the same bridge, on the same side, in the same municipality. The only differences in the titles are 'Construction' vs 'Rehabilitation/Improvement' and 'Barangay Ogob' vs 'Brgy. Comun-Ogob', which are not distinguishing markers per the rules (spelling/wording variants and barangay name variants are not distinguishing if they refer to the same area). Both projects are by the same contractor and have nearly identical costs. There is no phase, package, section, or station marker distinguishing them. Innocent explanation: one project may be a continuation or expansion of the other, or the second may be a repair of the first.
