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 22OC0136 and 23OC0019 have near-identical descriptions about 290 m apart (funding years 2022, 2023; ₱48.02M, ₱58.57M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or next phase of the first, but the first contract did not specify a phase.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase IV' in the second title, while the first title has no phase marker at all. Both projects are for the construction of a revetment wall along the same creek and barangay, funded in consecutive years, and are located only 290 meters apart. According to the rule guidance, if one title has a phase marker and the other does not, this should be published as a possible unlabelled twin or continuation. All necessary records and URLs are present.
