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 24II0040 and 22II0018 have near-identical descriptions about 34 m apart (funding years 2022, 2024; ₱48.96M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers additional improvements not included in the earlier contract.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with only the addition of 'Improvement' in one title, and no distinguishing markers such as phase, package, section, or different locations. Both projects are at nearly the same coordinates (34 meters apart), in the same municipality, and by the same contractor, but funded in different years. This fits the rule's criteria for a potentially duplicated or overlapping project. Innocent explanations are possible, but the evidence is sufficient and clear for public review.
