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 23BJ0032 and 23BJ0002 have near-identical descriptions about 372 m apart (funding year 2023; ₱96.50M, ₱48.24M). Worth checking whether they cover the same works. It is possible that these refer to adjacent or extended sections of the same flood control system, funded as separate contracts.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same general area (Comon Section vs Comon-Latar Section) in the same municipality, funded in the same year, and are only 372 meters apart. The only difference is the addition of 'Latar' in one title, which could indicate a slightly different or extended section, but it is not a clear phase/segment/lot marker or a completely different barangay. There are no distinguishing markers that would require rejection under the rule. Innocent explanation is plausible but does not block publishing.
