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 23BH0078 and 24BH0277 have near-identical descriptions about 267 m apart (funding years 2023, 2024; ₱49.00M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or a new section of the same flood control structure.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Section 1' in the second title, while the first title has no section/phase marker. Per rule guidance, if one title has a section/phase marker and the other does not, this is a classic 'unlabelled twin' case and should be published. The locations are close (267 m), and the titles are otherwise near-identical, both referring to the same structure and place. The evidence is complete and checkable.
