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. This may simply be a planned continuation or expansion of the original project, with the second contract covering a new 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 in the same municipality, funded in consecutive years. The only distinguishing marker is 'Phase II' in the second title, but the first title does not specify any phase, which fits the guidance for publishing as a possible unlabelled twin or continuation. The distance (202m) is close enough to plausibly be the same or overlapping works. All required records and URLs are present.
