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 23EA0051 and 23EA0013 have near-identical descriptions about 287 m apart (funding year 2023; ₱49.00M, ₱9.70M). Worth checking whether they cover the same works. It is possible these are two separate structures built in close proximity along the same river.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have near-identical titles, both in Barangay Banto, Mogpog, Marinduque, funded in the same year, and are only 287 meters apart. The only difference in the titles is the phrase 'along Mogpog River' in the first, which does not clearly distinguish the works as separate (since flood control structures in Barangay Banto are likely along the river). There are no phase, package, or section markers, and both are described as 'Construction of Flood Control Structure.' The evidence is complete and meets the rule's criteria for publishing.
