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 24OB0095 and 23OB0086 have near-identical descriptions about 1009 m apart (funding years 2023, 2024; ₱14.40M, ₱13.96M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or that 'P2B2' refers to a specific sub-area within Karangalan.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for the addition of 'P2B2' in the first title, which does not clearly indicate a distinct phase, package, or location marker. Both projects are in the same barangay, have the same contractor, and are about 1 km apart, with high title similarity (0.974). There are no distinguishing markers such as different phases, packages, or sitios. The only difference is the 'P2B2' term, which is not a standard phase or package marker and could plausibly refer to a sub-area but is not definitive. This fits the guidance for publishing as a possible duplicate or overlapping project.
