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 24OD0018 and 24OD0019 have near-identical descriptions about 312 m apart (funding year 2024; ₱47.95M, ₱47.93M). Worth checking whether they cover the same works. One contract may be a continuation or expansion of the other, but the lack of a phase marker in the second title makes this worth checking.

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 3' in one title, while the other has no phase or package marker. Per rule guidance, this is a classic 'unlabelled twin' case and should be published. The locations are close (312 m), the titles are otherwise near-identical, and both are in the same barangay and funding year. Innocent explanation: one contract may be a continuation or expansion of the other, but the lack of a phase marker in the second title makes this worth public attention.
