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 22DI0063 and 23DI0041 have near-identical descriptions about 2246 m apart (funding years 2022, 2023; ₱5.94M, ₱6.88M). Worth checking whether they cover the same works. It is possible these are separate drainage segments within the same barangay funded in different 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 and refer to the same barangay and municipality, with no distinguishing markers such as phase, package, or different sitios/sections. The only difference is the word 'in' in one title, which is not a distinguishing marker. The projects are about 2.2 km apart, which is plausible for drainage works in a large barangay, but the similarity in title and scope across consecutive years makes this a valid anomaly for public review.
