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 23HL0043 and 22HL0089 have near-identical descriptions about 91 m apart (funding years 2022, 2023; ₱49.00M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project, but this is not clearly labeled.

How this was checked

publish · confidence 0.92

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both refer to 'Construction of Maladpad River Control, Downstream' in the same municipality, and are only 91 meters apart. The only difference is 'Downstream A' vs '(downstream)', which does not clearly distinguish them as separate works per the rule guidance. No phase/section/segment or place marker is present in one but not the other. Both are large contracts (₱49M each) in consecutive years, and the evidence is complete.
