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 24CG0001 and 23CG0041 have near-identical descriptions about 108 m apart (funding years 2023, 2024; ₱91.84M, ₱91.63M). Worth checking whether they cover the same works. This may be a continuation or phased implementation of the same riverbank rehabilitation project.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase I' in the 2024 project, while the 2023 project has no phase or package marker. Per rule guidance, if one title has a phase/package marker and the other has none, this is a classic 'unlabelled twin' case and should be published. The locations are very close (108 m), the titles are otherwise near-identical, and both are in the same barangay and municipality. Innocent explanation is plausible (continuation or phased implementation), but the indicator is valid and worth public attention.
