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 23DF0031 and 22DF0008 have near-identical descriptions about 727 m apart (funding years 2022, 2023; ₱91.67M, ₱90.71M). Worth checking whether they cover the same works. It is possible that the second contract covers Phase I or an unlabelled section, and the works are part of a planned multi-phase project.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase II' in the first title, while the second title has no phase or package marker. According to the rule, if one title has a phase/package marker and the other has none, this is a publish case (unlabelled twin). The locations are within the same barangay and river, and the works are of the same type, funded in consecutive years. All required records and fields are present.
