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 23CD0061 and 22CD0102 have near-identical descriptions about 650 m apart (funding years 2022, 2023; ₱86.85M, ₱46.82M). Worth checking whether they cover the same works. The second contract may cover a different or broader section of the river, or be a continuation or adjacent segment not clearly labeled.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Although the first title specifies a particular section (Sta. 12+340-Sta. 12+740) and the second does not, the second title is generic and could plausibly overlap or duplicate the first, especially since both are for flood control structures along the same river in the same municipality and are only 650 meters apart. The only distinguishing marker is the stationing in the first title, but the absence of any marker in the second title means it could refer to the same or overlapping works. This fits the 'unlabelled twin' scenario described in the rule guidance.
