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 or overlapping area.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is that one title specifies '(Canturing-Nasaug Section)' while the other does not specify any section or phase. According to the rule, if one title has a section/phase marker and the other has none, this is considered a potential unlabelled twin and should be published. The locations are close (179 m apart), the funding year and contractor are the same, and the titles are otherwise nearly identical.
