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 22OC0136 and 23OC0017 have near-identical descriptions about 55 m apart (funding years 2022, 2023; ₱48.02M, ₱66.57M). Worth checking whether they cover the same works. The second project may be a continuation or extension of the first phase, but the first contract does not specify a phase.

How this was checked

publish · confidence 0.85

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 very close (55 m), and the rest of the title is near-identical, referring to the same creek and barangay. The evidence is complete and checkable.
