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. It is possible that the second contract is a continuation or expansion of the original project, or covers additional work not specified in the title.

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 place names that would indicate different works. The only differences are the funding years and contractors. This fits the rule's criteria for a potentially duplicated or repeated project at the same site. All necessary records and URLs are present for public checking.
