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 23CC0231 and 23CC0310 have near-identical descriptions about 978 m apart (funding year 2023; ₱67.53M, ₱57.90M). Worth checking whether they cover the same works. The two contracts may cover revetment works on different but nearby waterways within the same barangay.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for the water body named (Labangan Channel vs Hagonoy River), both are at Barangay Santa Elena, Hagonoy, Bulacan, funded in the same year, and are less than 1 km apart. There are no phase/package/section markers or other distinguishing markers. The only difference is the named water body, which could plausibly refer to adjacent or connected works, but could also indicate overlapping or duplicate coverage. This fits the rule's publish criteria.
