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 23HL0056 and 24HL0042 have near-identical descriptions about 372 m apart (funding years 2023, 2024; ₱36.26M, ₱45.08M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers an adjacent stretch of the river.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical and refer to the same river and municipality, with only a minor difference in word order and the presence of 'structure' in one title. There are no phase, package, section, or place markers that distinguish them as separate works. The locations are only 372 meters apart, and the funding years are consecutive. This fits the rule's criteria for a potentially duplicate or overlapping project. All necessary records and URLs are present.
