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 23CJ0028 and 23CJ0158 have near-identical descriptions about 281 m apart (funding year 2023; ₱47.53M, ₱49.50M). Worth checking whether they cover the same works. One project may be a continuation or a more focused portion of the other, or the scope may have been split between two contracts.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same dike and section, with the only difference being that one title covers 'Ayson to Dicolor Section' and the other just 'Dicolor Section'. This means the second project could be a subset of the first, or a continuation, but there is no clear phase/segment/lot marker distinguishing them as separate works. Both are in the same municipality, funded in the same year, and are only 281 meters apart. Innocent explanations exist, but the overlap is sufficient to warrant public attention.
