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 22A00122 and 23A00254 have near-identical descriptions about 1599 m apart (funding years 2022, 2023; ₱28.95M, ₱46.81M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, but this is not clearly labelled in the titles.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both project titles are near-identical, with no distinguishing markers or place names that would indicate different works. The only difference is a comma, which is not a distinguishing marker. The projects are about 1.6 km apart, which is outside the 100m threshold for identical-location flags, but the rule covers near-duplicates within the same municipality. The funding years are consecutive, and the package number is the same (Package 1), suggesting possible overlap or continuation without clear labelling. All required records and fields are present.
