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 22OF0075 and 23OF0030 have near-identical descriptions about 971 m apart (funding years 2022, 2023; ₱73.48M, ₱48.02M). Worth checking whether they cover the same works. It is possible that the second project is a planned continuation or expansion of the first, but the first contract did not specify a phase.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase 2' in the second title, while the first title has no phase marker. Per rule guidance, if one title has a phase marker and the other does not, this is a classic 'unlabelled twin' scenario and should be published. Both projects are in Barangay Gulod, Quezon City, and the titles are otherwise identical. The distance (971 m) is within the same barangay and does not indicate a different site. The evidence is complete and checkable.
