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 24A00240 and 23AE0041 have near-identical descriptions about 393 m apart (funding years 2023, 2024; ₱19.30M, ₱9.80M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a nearby but distinct section 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 project titles are near-identical, both refer to 'Flood Control Structure' at Barangay/Brgy. Antonino, Balaoan, La Union, and are only 393 meters apart. There are no distinguishing markers such as phase, package, section, or different sitios/barangays/structure types. The only differences are minor wording ('Barangay' vs 'Brgy.' and 'at'), which are not distinguishing per the rule. The funding years and contractors differ, but this does not explain the near-duplicate titles and locations.
