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 24CC0055 and 24CC0039 have near-identical descriptions about 274 m apart (funding year 2024; ₱99.00M, ₱96.50M). Worth checking whether they cover the same works. One project may be a continuation or separate phase, but the other 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 III' in one title, while the other has no phase or package marker. Per rule guidance, this is a classic 'unlabelled twin' case and should be published. Both projects are in the same barangay, same year, and have near-identical titles and scopes, with substantial contract amounts and only 274 meters apart. Innocent explanation is plausible but does not block publication.
