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 22DL0069 and 22DL0070 have near-identical descriptions at the same coordinates (funding year 2022; ₱92.84M, ₱19.60M). Worth checking whether they cover the same works. It is possible that the two contracts cover different components (flood control vs. drainage) at the same site.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects have identical coordinates and near-identical titles, with the only difference being the addition of 'and Drainage Structure' in the second title. There are no phase, package, section, or place markers distinguishing them, and both are in the same municipality and year. This fits the rule's criteria for a potentially overlapping or duplicate project.
