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 22OI0112 and 22OI0135 have near-identical descriptions about 675 m apart (funding year 2022; ₱14.69M, ₱19.59M). Worth checking whether they cover the same works. One project may cover only drainage, while the other includes both road and drainage works in the same barangay.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both project titles refer to rehabilitation works in Barangay Pamplona 1, Las Piñas City, funded in the same year, by the same contractor, and are only 675 meters apart. The only differences in the titles are the inclusion of 'Road and Drainage System' versus just 'Drainage', with no phase, package, or section markers, and both refer to the same barangay. This fits the rule's criteria for a potentially overlapping or duplicate project, as there is no clear distinguishing marker indicating they are separate works.
