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 23AA0148 and 24AA0093 have near-identical descriptions about 1439 m apart (funding years 2023, 2024; ₱29.40M, ₱29.40M). Worth checking whether they cover the same works. It is possible that these are sequential or adjacent segments of flood control works funded in different years.

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, both for 'Construction of Flood Control Structure' at Barangay Cabaruan, Bacarra, Ilocos Norte, with only the first title specifying 'along Bislak River.' There are no phase, package, section, or other distinguishing markers, and both are in the same barangay. The distance between the coordinates (1439 m) is above the strict threshold for 'nearby,' but the titles overlap in scope and location, and the only difference is the mention of the river, which is not a unique distinguishing marker for this context. The evidence is complete and checkable.
