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 24BC0086 and 22BC0085 have near-identical descriptions about 1050 m apart (funding years 2022, 2024; ₱48.96M, ₱26.46M). Worth checking whether they cover the same works. It is possible that the 2024 project is a continuation or expansion of the 2022 works in the same area.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both refer to 'Simayung Flood Control' along the Abulug River in Abulug, Cagayan, and there are no distinguishing markers such as different phases, sections, or barangays. The only difference is the word 'Structure' and the explicit mention of 'Simayung' in the second title, but both are in the same area and refer to the same type of work. The projects are about 1 km apart, which is plausible for overlapping or repeated works. The evidence is complete and meets the rule's criteria.
