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 23OF0026 and 22OF0026 have near-identical descriptions about 4126 m apart (funding years 2022, 2023; ₱29.40M, ₱73.29M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or separate phase of the first, or covers a different section not specified in the title.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Although one title includes 'Phase 2' and the other does not, the guidance specifies to publish when the only difference is a phase marker and the other title is unlabelled. Both projects are in Barangay Sta. Lucia, Quezon City, and the titles are otherwise near-identical. The distance (4.1 km) is not so great as to clearly indicate different barangays or sites, and the possibility of unlabelled continuation or overlapping scope is present. The evidence is complete and checkable.
