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 project is a continuation or expansion of the first, or that the same area required additional works in the following year.

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, both refer to 'Amobocan, Flood Control Project (Package 1)' in Cauayan, Isabela, and are only 14 meters apart. The only difference in the titles is the presence of the word 'City' in the second title, which is not a distinguishing marker per the rules (spelling/wording variants like 'Cauayan' vs 'Cauayan City' are not distinguishing). Both projects are in the same barangay/spot, funded in consecutive years, and there is no phase/section/segment/lot marker that distinguishes them. All required records are present.
