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 22DN0112 and 22DN0140 have near-identical descriptions about 88 m apart (funding year 2022; ₱9.90M, ₱9.80M). Worth checking whether they cover the same works. It is possible that one contract is a continuation or extension of the other, or that the works are adjacent but separately contracted.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both titles refer to the construction of a breakwater structure in Barangay Janosa, Binangonan, Rizal, funded in the same year, with locations only 88 meters apart. The only differences in the titles are 'Continuation' and the spelling variant 'Brgy.' vs 'Barangay', which are not distinguishing markers per the rule. There are no phase, package, section, or site markers that would indicate these are distinct works. The evidence is complete and meets the rule's criteria for a plausible duplicate or overlapping project.
