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 22FB0190 and 23FB0006 have near-identical descriptions about 362 m apart (funding years 2022, 2023; ₱49.00M, ₱57.73M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project, but this is not specified in the titles.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two contracts have identical titles with no distinguishing markers, are located in the same municipality, and are only 362 meters apart. The only differences are the funding years and contractors, which does not explain the identical scope. This fits the rule's criteria for a potentially duplicated or overlapping project. All necessary records and URLs are present.
