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 24HF0004 and 23HF0014 have near-identical descriptions about 1947 m apart (funding years 2023, 2024; ₱96.20M, ₱66.95M). 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 a different stretch of the same river.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have identical titles with no distinguishing markers, are in the same barangay and sitio, and are funded in consecutive years. The distance between the coordinates (1947 m) is above the 100 m threshold, but the rule is for near-identical titles within the same municipality, and the code has already flagged this as a valid case. There is no evidence in the packet that these are distinct works (e.g., different phases, sections, or locations).
