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 24CC0042 and 24CC0041 have near-identical descriptions about 1447 m apart (funding year 2024; ₱96.50M, ₱99.00M). Worth checking whether they cover the same works. It is possible that these are sequential phases of a larger project, with one phase simply not labeled as such.

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 the rule-specific 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 packet contains all necessary records and URLs for public checking.
