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 23CE0032 and 24CE0219 have near-identical descriptions about 1208 m apart (funding years 2023, 2024; ₱48.01M, ₱28.66M). Worth checking whether they cover the same works. It is possible that the second contract is a planned continuation or expansion of the first project.

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same river and barangay, with the only distinguishing marker being 'Phase 2' in the second title. Per the rule, if one title has a phase marker and the other does not, this is considered a potential unlabelled twin and should be published. The evidence is complete, with contract IDs, URLs, and location data provided.
