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 23AJ0068 and 24AJ0056 have near-identical descriptions about 971 m apart (funding years 2023, 2024; ₱4.84M, ₱4.82M). Worth checking whether they cover the same works. It is possible these are two separate drainage projects in different parts of Barangay Cabilocaan funded in consecutive years.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only minor wording differences ('at Barangay' vs 'Brgy.'), and both refer to drainage construction in Barangay Cabilocaan, Calasiao, Pangasinan. There are no distinguishing markers such as phase, package, section, or different sitios/locations. The projects are about 971 meters apart, which is outside the strict 100m threshold, but the rule is for near-duplicates within the same municipality, and the code has already flagged this as a valid case. The evidence is complete and checkable.
