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 24AF0095 and 24AF0111 have near-identical descriptions about 137 m apart (funding year 2024; ₱96.49M, ₱89.74M). Worth checking whether they cover the same works. One contract may be a specific package of a larger project, while the other covers the general works.

How this was checked

publish · confidence 0.70

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. The locations are very close (137 m), the titles are otherwise near-identical, and both are in the same municipality and funding year. Innocent explanation is plausible but does not block publishing.
