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 22HJ0029 and 24HJ0021 have near-identical descriptions at the same coordinates (funding years 2022, 2024; ₱14.70M, ₱29.40M). Worth checking whether they cover the same works. The second contract may be a continuation or extension of the first, but the title does not specify the segment covered.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is that one title specifies 'Sta. 0+000 - Sta. 0+750' while the other does not mention any stationing or segment. Per the rule, 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 coordinates are identical, and the titles otherwise match, so it is plausible these refer to the same or overlapping works, or a continuation that is not clearly labelled as such.
