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 24OG0021 and 23OG0072 have near-identical descriptions about 54 m apart (funding years 2023, 2024; ₱49.00M, ₱9.76M). Worth checking whether they cover the same works. The 2023 contract may have been an initial phase, with the 2024 contract as a planned continuation.

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 2' in the 2024 project, while the 2023 project has no phase/segment marker. Per rule guidance, this is a classic 'unlabelled twin' case: the earlier project may be a first phase or a smaller scope, but the lack of explicit phase/segment/section in one title means the public should see this as a possible double funding or continuation without clear labelling. The packet provides all necessary record IDs, URLs, and figures for public checking.
