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 23LC0071 and 24LC0073 have near-identical descriptions about 294 m apart (funding years 2023, 2024; ₱148.47M, ₱148.50M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first phase, but this is not clearly labeled in the titles.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with no distinguishing markers or place names that would indicate different works. Both are for flood control structures along Hijo River in Brgy. Madaum, Tagum City, funded in consecutive years, and are located only 294 meters apart. The only differences in the titles are word order and the presence/absence of 'Hijo River' at the start, which does not constitute a distinguishing marker. This fits the rule's publish criteria for possible duplicate or overlapping works.
