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 23BG0012 and 24BG0007 have near-identical descriptions about 105 m apart (funding years 2023, 2024; ₱24.13M, ₱96.48M). Worth checking whether they cover the same works. The second contract may simply be a 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 only 105 meters apart, and the titles are otherwise near-identical, both referring to the same barangay and project type. Innocent explanation: the second contract may be a continuation or expansion of the first, but the lack of a phase marker in the first title makes it worth flagging.
