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 23KE0031 and 24KE0015 have near-identical descriptions about 397 m apart (funding years 2023, 2024; ₱46.94M, ₱9.51M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the first project.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only minor spelling differences ("Rd" vs "Road") and no distinguishing markers such as phase, package, section, or different place names. Both projects are at nearly the same location (397 meters apart), in the same municipality, and by the same contractor, but funded in consecutive years. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations are possible, but the evidence is sufficient and clear for public review.
