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 22HO0002 and 23HO0223 have near-identical descriptions about 250 m apart (funding years 2022, 2023; ₱48.32M, ₱87.81M). Worth checking whether they cover the same works. This may be a legitimate continuation or expansion of the same project area.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase II' in the second title, while the first title has no phase marker. Per rule guidance, if one title has a phase marker and the other does not, this is considered a potential unlabelled twin and should be published. The locations are very close (250m), the titles are otherwise identical, and both are in the same barangay and municipality. Innocent explanation: this may be a legitimate continuation or expansion of the same project area, but the lack of a phase marker in the first title makes it worth public review.
