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 in the same city, with one specifically in Barangay Zone 1 and the other in a different or broader area.

How this was checked

publish · confidence 0.70

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, 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 outside the strict 100m threshold for 'identical coordinates', but the rule covers near-identical titles within the same municipality as well. The evidence is complete and the public can check the records.
