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 22IG0010 and 23IG0056 have near-identical descriptions at the same coordinates (funding years 2022, 2023; ₱48.34M, ₱48.22M). Worth checking whether they cover the same works. This may be a continuation or expansion of the same flood control project funded in consecutive years.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two contracts have identical coordinates and exactly matching titles, with no distinguishing markers or words. They are in consecutive years, at the same location, and the packet contains all necessary record details for public review. Innocent explanations (such as a continuation or expansion of works) are plausible but do not negate the anomaly.
