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 24AF0055 and 24AF0014 have near-identical descriptions about 443 m apart (funding year 2024; ₱96.49M, ₱48.74M). Worth checking whether they cover the same works. It is possible these are separate segments or phases of flood control works in the same barangay, handled by different contractors.

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 refer to the Bauang River Basin in Barangay (Sto.) Cabaritan Sur, Naguilian, La Union, and are funded in the same year. The only differences are the presence of 'Sto.' in one title and the singular/plural form of 'Structure/Structures', which are not distinguishing markers per the rule. The projects are about 443 meters apart, which is above the 100m threshold but still close enough to warrant public attention, especially since both are completed in 2024 and have substantial contract values. There is no evidence of a data artifact or clear distinction in scope or location.
