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 24NC0004 and 23NC0033 have near-identical descriptions about 18 m apart (funding years 2023, 2024; ₱7.92M, ₱9.80M). 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 works not specified in the title.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, with the only difference being the word 'Structure' in one title. There are no phase, package, section, or place markers distinguishing them, and both are at the same barangay and within 18 meters of each other. This fits the rule's criteria for a potentially duplicate or overlapping project. The evidence is complete and checkable.
