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 23CI0118 and 23CI0132 have near-identical descriptions at the same coordinates (funding year 2023; ₱69.21M, ₱19.72M). Worth checking whether they cover the same works. One project may cover a longer stretch or include repairs, while the other focuses on new construction at a specific segment.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects are at identical coordinates, funded in the same year, and their titles are highly similar, both describing slope protection works along Sapangbalen/Sapang Balen in Brgy. Sta. Maria, Magalang, Pampanga. The only differences are that one title mentions 'Creek' and 'from Brgy. San Ildefonso to Brgy. Sta. Maria' and includes 'Repair', while the other mentions 'River' and only Brgy. Sta. Maria. There are no phase, package, or section markers, and the distinguishingMarkers fields are empty. The overlap in location and scope is strong enough to warrant public attention, as the works may cover the same or overlapping stretches, or one may be a subset of the other.
