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 23OE0072 and 24OE0002 have near-identical descriptions about 2 m apart (funding years 2023, 2024; ₱47.75M, ₱64.21M). Worth checking whether they cover the same works. The second contract may be a planned continuation or expansion of the first project.

How this was checked

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 a classic 'unlabelled twin' scenario and should be published. The locations are nearly identical (2 meters apart), and the rest of the title is the same, with no other distinguishing place or structure markers.
