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 24NE0025 and 22NE0038 have near-identical descriptions about 222 m apart (funding years 2022, 2024; ₱57.19M, ₱29.70M). Worth checking whether they cover the same works. One project may focus on the area around Tag-iho Bridge I, while the other covers a broader section of Barangay Tag-abaca.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical and refer to the same barangay and municipality, with only minor differences: one specifies 'at Tag-iho Bridge I' while the other uses 'Barangay Tag-abaca'. There are no phase, package, or section markers, and both are within 222 meters of each other. The difference in title wording does not clearly indicate distinct works, so this fits the rule's guidance for publishing. Innocent explanations (e.g., one project is for the bridge area, the other for a broader barangay section) are plausible but do not block publication.
