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 23NC0020 and 24NC0029 have near-identical descriptions about 202 m apart (funding years 2023, 2024; ₱49.00M, ₱67.55M). Worth checking whether they cover the same works. The second project may be a planned continuation or expansion of the first phase.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same river bank protection at the same bridge approach and upstream location, funded in consecutive years. The only distinguishing marker is 'Phase II' in the second title, while the first has no phase marker. Per rule guidance, if one title has a phase marker and the other does not, this is a classic 'unlabelled twin' case and should be published. The 202 m distance is within the expected margin for such works. All required record details and URLs are present.
