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 24CC0001 and 22CC0187 have near-identical descriptions about 596 m apart (funding years 2022, 2024; ₱96.50M, ₱57.90M). Worth checking whether they cover the same works. This may be a continuation or extension of riverbank protection works 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 river and barangay, with only minor wording differences (Barangay vs Brgy, and 'Structure' present in one title). There are no distinguishing markers such as different phases, sections, or locations. The projects are about 596 meters apart, which is outside the strict 100m threshold, but the rule is for near-duplicates within the same municipality, and the code has flagged this as a valid case. Innocent explanations such as a continuation or extension of works are plausible, but the indicator is worth showing.
