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 22IL0025 and 23IL0043 have near-identical descriptions about 35 m apart (funding years 2022, 2023; ₱49.00M, ₱4.88M). Worth checking whether they cover the same works. It is possible the second project is a continuation or expansion of the first to cover an adjacent area.

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 general location (Bato I/1, Maasin City), with no distinguishing phase, package, or section markers. The only difference is that one title mentions 'Bato I' and the other 'Barangay Bato 1 to 2', which could indicate a slightly broader scope for the second project, but not enough to clearly distinguish them as separate works. The projects are only 35 meters apart and funded in consecutive years, making it plausible they could cover the same or overlapping works. All necessary record links and figures are present.
