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 22IJ0090 and 22IJ0084 have near-identical descriptions about 191 m apart (funding year 2022; ₱28.73M, ₱38.91M). Worth checking whether they cover the same works. It is possible that the second contract simply extends the scope to cover an additional barangay.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, both refer to rehabilitation of flood control structures along the same river and barangay (Brgy. Burabod II), with one title simply adding 'and Brgy. Dumaloong'. There are no phase, package, or section markers distinguishing them, and the only difference is the inclusion of an additional barangay in one title. The locations are only 191 meters apart, and both projects are in the same funding year with the same contractor. This fits the guidance for publishing: one title is the other plus an extra place, which is considered overlapping scope.
