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 23GK0067 and 22GK0126 have near-identical descriptions about 1144 m apart (funding years 2022, 2023; ₱4.95M, ₱4.95M). Worth checking whether they cover the same works. It is possible that the two contracts cover different sections of drainage within the city, with one specifically in Barangay Zone 1 and the other in a different or broader area.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, with the only difference being that one specifies 'Barangay Zone 1' while the other does not specify a barangay or zone. According to the rule guidance, if one title has a barangay/zone marker and the other does not, this is considered a potential unlabelled twin and should be published. The projects are about 1.1 km apart, which is within the same city and could plausibly refer to the same or overlapping works, especially since both are for drainage construction, have the same contractor, and similar costs. The evidence is complete and checkable.
