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 24CD0011 and 24CD0012 have near-identical descriptions about 183 m apart (funding year 2024; ₱49.50M, ₱47.52M). Worth checking whether they cover the same works. One contract may be for a specific segment, while the other covers a broader or overlapping area.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is that one title specifies 'Sta. 09 + 300 to Sta. 09 + 500' while the other does not mention any station/chainage. According to the rule guidance, if one title has a phase/station marker and the other has none, this is a classic 'unlabelled twin' case and should be published. The locations are close (183m), the titles are highly similar, and both are in the same funding year, municipality, and section. Innocent explanation is plausible but does not block publishing.
