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 22CI0057 and 22CI0058 have near-identical descriptions at the same coordinates (funding year 2022; ₱23.75M, ₱24.30M). Worth checking whether they cover the same works. It is possible that the second contract covers an extension or additional segment not specified in the first title.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects have identical coordinates and highly overlapping titles, with the only differences being that one title lists additional locations (Marcos Village, Sapangbalen Riverwall, Sta. markers) while the other is more general. There are no phase/package/section markers or clearly distinguishing features that would indicate these are separate, non-overlapping works. The overlap in location and scope, same contractor, and same funding year make this a valid anomaly for public review.
