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 24AJ0025 and 23AJ0125 have near-identical descriptions about 259 m apart (funding years 2023, 2024; ₱48.13M, ₱18.98M). Worth checking whether they cover the same works. The 2024 project may simply be a continuation or next phase of the 2023 project.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase III' 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 close (259 m), titles are otherwise near-identical, and both are in the same barangay and municipality. Innocent explanation: the 2024 project may be a continuation or next phase of the 2023 project, but the earlier project does not specify a phase, so possible overlap or double funding is worth public attention.
