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 24AF0141 and 24AF0051 have near-identical descriptions about 543 m apart (funding year 2024; ₱19.28M, ₱29.69M). Worth checking whether they cover the same works. One project may be a continuation or sub-package of the other, but the titles do not make this clear.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Package 4' in the second title, while the first title has no package/phase marker. Per rule guidance, if one title has a package marker and the other does not, this is a classic 'unlabelled twin' case and should be published. Both projects are in the same barangay, municipality, and year, with near-identical titles and the same contractor. Innocent explanations (such as one being a continuation or a sub-package) are plausible but do not block publication.
