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 24BA0017 and 23BA0002 have near-identical descriptions about 72 m apart (funding years 2023, 2024; ₱9.78M, ₱9.74M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or second phase of the first project, but the earlier contract did not specify a phase.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the first title, while the second title has no phase or package marker. According to the rule-specific guidance, if one title has a phase/package marker and the other has none, this should be published as a possible unlabelled twin or continuation. The packet provides all necessary details, including record IDs, URLs, and coordinates.
