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 23CI0116 and 23CI0149 have near-identical descriptions at the same coordinates (funding year 2023; ₱48.38M, ₱4.85M). Worth checking whether they cover the same works. One project may be a smaller component or a specific structure within the larger slope protection work.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects are at identical coordinates, in the same barangay, same year, and the titles overlap in scope. The only differences in the titles are descriptive (materials, structure details, and location specifics), not phase/package/section markers or different sites. No distinguishing marker is present that would indicate these are clearly separate works. Innocent explanations (e.g., one is a subcomponent or extension of the other, or covers a specific structure type) are plausible but do not negate the anomaly.
