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 23CC0124 and 23CC0141 have near-identical descriptions at the same coordinates (funding year 2023; ₱77.20M, ₱28.95M). Worth checking whether they cover the same works. One project may be a specific structure (revetment) within a larger flood mitigation effort.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects are at identical coordinates, in the same barangay and municipality, funded in the same year, and the titles are overlapping in scope (both refer to Matungao, Bulacan/Bulakan, Bulacan). There are no distinguishing phase, package, or section markers, and the only differences in the titles are generic (e.g., 'Flood Mitigation Structures' vs 'Revetment'). This fits the rule's criteria for a potentially overlapping or duplicate project. Innocent explanations are possible, such as the revetment being a specific structure within a broader flood mitigation project, but the overlap is sufficient to warrant public attention.
