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 24CC0396 and 24CC0395 have near-identical descriptions about 213 m apart (funding year 2024; ₱77.20M, ₱77.20M). Worth checking whether they cover the same works. One contract may specifically cover Purok 2, while the other covers the rest of the Culianin Section.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only difference between the two titles is the mention of '(Purok 2)' in the first title, while the second title omits any purok or other distinguishing marker. According to the rule, if one title has a phase/package/area marker and the other has none, this is considered a potential unlabelled twin and should be published. The locations are close (213 m apart), the funding year is the same, and the contract values are nearly identical. There is no clear evidence that these are distinct works, so the indicator is worth showing.
