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 24MH0030 and 23MH0078 have near-identical descriptions about 490 m apart (funding years 2023, 2024; ₱4.94M, ₱4.95M). Worth checking whether they cover the same works. It is possible these are two phases or extensions of flood control works in 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, both refer to 'Flood Control' in Barangay/Brgy. Poblacion, Kalamansig, Sultan Kudarat, and the only differences are generic words ('Structure', 'Barangay' vs 'Brgy'), which are not distinguishing markers. The projects are about 490 meters apart and funded in consecutive years, which fits the rule's intent to flag possible duplicate or overlapping works. There are no phase, package, section, or site markers that would distinguish them as separate works.
