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 23CH0044 and 23CH0060 have near-identical descriptions about 1469 m apart (funding year 2023; ₱29.40M, ₱19.59M). Worth checking whether they cover the same works. These may be separate works along different parts of Sta. Catalina, with one specifically for Sapang Gumi.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, both for slope protection in Sta. Catalina, Lubao, Pampanga, funded in the same year. The only difference is that one title specifies 'Sapang Gumi' (likely a creek or sub-location) while the other does not. There are no phase, package, or section markers, and 'Sapang Gumi' could be a part of Sta. Catalina, so the overlap is significant enough to warrant public attention. Innocent explanation: the projects may cover adjacent or related stretches, with one specifically targeting Sapang Gumi and the other a broader or different area within Sta. Catalina.
