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 24BC0084 and 23BC0018 have near-identical descriptions about 653 m apart (funding years 2023, 2024; ₱48.25M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first.

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 municipality, and are only 653 meters apart. The only difference is the funding year and contractor. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations (such as a continuation or expansion of works) are plausible but do not negate the anomaly.
