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 23I00017 and 23IF0071 have near-identical descriptions about 13 m apart (funding year 2023; ₱96.36M, ₱96.50M). Worth checking whether they cover the same works. One contract may cover the downstream section, while the other covers the rest of the flood control structure.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'downstream' in the first title, while the second title has no such marker. Per the rule, if one title has a phase/segment marker and the other has none, this is a classic 'unlabelled twin' case and should be published. The locations are only 13 meters apart, and both are in the same barangay and municipality, with near-identical titles and funding years. Innocent explanations are possible (e.g., one contract covers downstream, the other covers the rest), but the lack of a clear marker in the second title makes this worth public attention.
