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 22IL0080 and 22IL0087 have near-identical descriptions about 179 m apart (funding year 2022; ₱24.72M, ₱48.94M). Worth checking whether they cover the same works. One contract may cover a specific section while the other covers a broader area, or the section may be part of the larger project.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'section' and a specific section name ('Canturing-Nasaug Section') in the first title, while the second title is more general ('Canturing'). According to the rule, if one title has a section marker and the other does not, this is a classic 'unlabelled twin' case and should be published. The locations are close (179 m), the titles are highly similar, and both are in the same funding year and municipality with the same contractor. Innocent explanation: the more general contract may cover a broader area, or the section may be a subset, but the overlap is not clearly labelled.
