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 23CH0048 and 22CH0043 have near-identical descriptions about 379 m apart (funding years 2022, 2023; ₱28.70M, ₱48.85M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or a different phase that was not labeled as such.

How this was checked

publish · confidence 0.78

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase I' in the first title, while the second title has no phase or package marker. Per rule guidance, if one title has a phase/package marker and the other has none, this is a classic 'unlabelled twin' case and should be published. The locations are close (379 m), titles are highly similar, and both are in the same section of the river in the same barangay. All required records and fields are present.
