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 23BC0021 and 22BC0119 have near-identical descriptions about 964 m apart (funding years 2022, 2023; ₱48.25M, ₱19.60M). Worth checking whether they cover the same works. It is possible that the two contracts cover adjacent or sequential sections of the river, or that one is a continuation or expansion of the other.

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 flood control structures along the same river in the same municipality, and the only difference is that one title includes 'Capanikkian-Nagsabaran' while the other has just 'Nagsabaran'. There are no phase, package, section, or station markers, and 'Capanikkian-Nagsabaran' could plausibly refer to a broader or overlapping area that includes 'Nagsabaran'. The projects are about 964 meters apart, which is within a plausible range for overlapping or adjacent works. The evidence is complete and the indicator is worth showing the public.
