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 24HO0016 and 23HO0004 have near-identical descriptions about 86 m apart (funding years 2023, 2024; ₱128.18M, ₱96.21M). Worth checking whether they cover the same works. The second project may simply extend the revetment wall to cover an additional sitio.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical and refer to the same sitio (Luwak) and barangay (Salmeron), with one title also mentioning Sitio Kang-Irong. The only additional marker is the inclusion of another sitio in the second title, which means the second project could cover a larger area, but the overlap at Sitio Luwak is clear. There are no phase/package/section markers distinguishing them as separate works. The projects are only 86 meters apart, funded in consecutive years, and have the same contractor. This fits the rule's publish criteria for possible duplicate or overlapping works.
