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 24JE0032 and 23JE0075 have near-identical descriptions about 43 m apart (funding years 2023, 2024; ₱29.37M, ₱78.40M). Worth checking whether they cover the same works. One project may have included an access road while the other focused solely on the river control structure.

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, both refer to the same creek and barangay, and are only 43 meters apart. The only differences are the inclusion of 'with Access Road' in one title and minor wording differences ('Barangay' vs 'Brgy.'). There are no phase, package, section, or site markers distinguishing them as separate works. This fits the rule's criteria for a potentially overlapping or repeated project.
