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 24DL0064 and 23DL0089 have near-identical descriptions about 240 m apart (funding years 2023, 2024; ₱67.55M, ₱44.10M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or additional phase of the first, but only one was labeled as a package.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical except for 'Package A' in the second title, which per rule guidance is not a distinguishing marker if the other title has no package/phase marker. Both projects are in the same municipality, funded in consecutive years, by the same contractor, and are only 240 meters apart. There are no other distinguishing markers or place names. This fits the 'unlabelled twin' scenario described in the rule guidance.
