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 22FA0014 and 23FA0037 have near-identical descriptions about 950 m apart (funding years 2022, 2023; ₱94.57M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second contract is a planned continuation or extension of the first project.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase marker. Per rule guidance, this is a classic 'unlabelled twin' case: one project is explicitly marked as a phase, the other is not, and both are at the same site with near-identical titles and a one-year funding gap. No other distinguishing markers or place names are present. The evidence is complete and checkable.
