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 22GM0022 and 23GM0013 have near-identical descriptions about 668 m apart (funding years 2022, 2023; ₱49.00M, ₱89.26M). Worth checking whether they cover the same works. This may be a multi-phase project where only one phase was explicitly labelled.

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 1' 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 close (668 m), the titles are otherwise near-identical, and both are in the same municipality and river section. Innocent explanation is plausible (e.g., a multi-phase project where only one phase is labelled), but this is exactly the kind of pattern the rule is meant to surface.
