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 22CN0182 and 24CN0079 have near-identical descriptions about 660 m apart (funding years 2022, 2024; ₱49.00M, ₱31.36M). Worth checking whether they cover the same works. The second project may be a continuation or an extension at a specific site (Cabulao Creek) within the same barangay.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both project titles refer to flood control structures in Barangay/Brgy. Paltic, Dingalan, Aurora, funded in different years and located about 660 meters apart. The only additional marker in the second title is 'Cabulao Creek,' which could be a specific site within the barangay, but both works are described at the same barangay level and the first title is broad enough to potentially include the second. There are no explicit phase, package, or section markers distinguishing them as separate works. Innocent overlap or continuation is plausible, but the similarity and proximity warrant public attention.
