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 22CK0102 and 24CK0072 have near-identical descriptions about 6725 m apart (funding years 2022, 2024; ₱50.17M, ₱96.50M). Worth checking whether they cover the same works. It is possible that 'Package F' is a continuation or expansion of the earlier project, or covers a different portion of the same dike section.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only difference between the two titles is the addition of 'Package F' in the second title, with no phase/section/segment/structure or place marker distinguishing them. According to the rule, if one title has a package marker and the other does not, and there are no other distinguishing markers, this should be published as a potential unlabelled twin or continuation. The projects are in the same municipality, have very similar titles, and are about 6.7 km apart, which is within the same river section and could plausibly be a continuation or a repeat funding for the same or overlapping works.
