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 22ME0070 and 24ME0062 have near-identical descriptions about 324 m apart (funding years 2022, 2024; ₱96.41M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or addresses a different segment of the same river.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both referring to 'Construction of Maribulan [River/Flood] Control' in Alabel, Sarangani, with no distinguishing phase, package, section, or place markers. The only difference is 'River' vs 'Flood', which are not distinguishing in this context, and both refer to flood mitigation structures. The projects are about 324 meters apart, within the threshold for possible duplicate or overlapping works. The evidence is complete and checkable.
