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 24AA0085 and 24AA0086 have near-identical descriptions about 106 m apart (funding year 2024; ₱19.60M, ₱49.00M). 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

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase/package marker. Per rule guidance, this is a classic 'unlabelled twin' case and should be published. Both projects are in the same barangay, same river, and are only 106 meters apart, with near-identical titles except for the phase marker.
