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 22IE0059 and 22IE0060 have near-identical descriptions at the same coordinates (funding year 2022; ₱4.80M, ₱4.80M). Worth checking whether they cover the same works. It is possible that the first contract was simply not labeled as a phase, and these are sequential phases of the same project.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase II' in the second title, while the first title has no phase marker at all. Per rule guidance, this is a classic 'unlabelled twin' case and should be published. Both projects are at the exact same coordinates, have near-identical titles, the same contractor, and the same funding year, making it plausible they refer to the same or overlapping works, or a continuation that was not clearly labelled in the first contract.
