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 24BH0054 and 23BH0059 have near-identical descriptions about 14 m apart (funding years 2023, 2024; ₱70.83M, ₱29.40M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project, or that the same site received funding in consecutive years.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both refer to 'Construction of Amobocan, Flood Control Project (Package 1)' at Amobocan, Cauayan, Isabela, and are only 14 meters apart. The only difference is the presence of 'City' in one title, which is not a distinguishing marker per the rules. There are no phase, package, section, or site markers that distinguish the works. The evidence is complete and the indicator is worth showing.
