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 22AH0144 and 22AH0126 have near-identical descriptions about 1071 m apart (funding year 2022; ₱29.70M, ₱24.01M). Worth checking whether they cover the same works. It is possible these are two separate stretches of riverbank protection within the same barangay.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to 'Construction of Riverbank Protection' at 'Brgy. Sapang, Manaoag, Pangasinan', and there are no distinguishing markers such as phase, package, section, or different sitios/barangays. The only difference is the word 'at', which is not a distinguishing marker. Both projects are in the same barangay and municipality, funded in the same year, but are about 1 km apart. This fits the rule's criteria for a potentially overlapping or duplicate project. Innocent explanations (e.g., two separate stretches of riverbank protection in the same barangay) are plausible but do not block publishing.
