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 24CH0065 and 22CH0054 have near-identical descriptions about 228 m apart (funding years 2022, 2024; ₱14.84M, ₱48.84M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers additional works in the same area.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for a minor spelling error ('Constuction' vs 'Construction'), and both refer to the same section of the Porac River in Floridablanca, Pampanga. There are no distinguishing markers such as different phases, packages, or locations. The projects are about 228 meters apart, which is slightly above the 100m threshold, but the high title similarity and lack of distinguishing markers make this a plausible case of potential duplicate or overlapping works. All necessary records and URLs are present.
