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 24HL0013 and 23HL0005 have near-identical descriptions about 211 m apart (funding years 2023, 2024; ₱45.08M, ₱44.10M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or that additional repairs were needed after the initial work.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have near-identical titles with no distinguishing markers, are located only 211 meters apart, and are funded in consecutive years. There are no phase, package, or location differences in the titles, and both refer to the same river section and barangay. This fits the rule's criteria for a potentially duplicated or overlapping project. Innocent explanations are possible but do not block publication.
