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 24FK0047 and 23FK0052 have near-identical descriptions about 271 m apart (funding years 2023, 2024; ₱9.90M, ₱18.13M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers an adjacent section not clearly labeled in the title.

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 'Construction of River Control' at the same barangay and city, and are only 271 meters apart. The only difference in the titles is the word 'Structure' in one, which is not a distinguishing marker per the rules. There are no phase, package, section, or place markers that distinguish them. The funding years and contractors differ, but this does not explain the near-duplicate scope. The evidence is complete and checkable.
