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 23IM0046 and 23IM0056 have near-identical descriptions about 20 m apart (funding year 2023; ₱48.54M, ₱55.43M). Worth checking whether they cover the same works. It is possible that these are sequential phases of a larger project, with the first contract simply not labeled as 'Phase 1.'

How this was checked

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase or package marker. Per the rule-specific guidance, this is a classic 'unlabelled twin' case and should be published. Both projects are in the same year, at nearly identical locations, and the titles are otherwise identical. The evidence is complete and checkable.
