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 24CK0072 and 23CK0043 have near-identical descriptions about 649 m apart (funding years 2023, 2024; ₱96.50M, ₱47.70M). Worth checking whether they cover the same works. It is possible that 'Package F' is just a continuation or a new phase of the same project area funded in a different year.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only difference between the titles is the presence of 'Package F' in the first title, with no phase/section/segment/side or place marker distinguishing the works. According to the rule, if one title has a package marker and the other does not, this is a classic 'unlabelled twin' case and should be published. The projects are in the same section of the river, same municipality, and are about 649 meters apart, which is within a plausible range for overlapping or repeated works. The evidence is complete and the public text is clear.
