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 24N00088 and 23N00119 have near-identical descriptions about 90 m apart (funding years 2023, 2024; ₱193.00M, ₱113.87M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the same works, or covers additional repairs needed after the first project.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have identical titles (including Package 2, Barangay, river, and structure), are only 90 meters apart, and are funded in consecutive years by the same contractor. There are no distinguishing markers or words in the titles to indicate they are different works or phases. This fits the rule's publish criteria for possible duplicate or overlapping funding.
