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 22DO0010 and 23DO0088 have near-identical descriptions about 1058 m apart (funding years 2022, 2023; ₱48.51M, ₱20.06M). Worth checking whether they cover the same works. It is possible these are separate segments of flood control works along the same river, funded in different years.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and both refer to flood control structures along the Upper Marikina in Rodriguez, Rizal, funded in consecutive years. The only additional words in the second title are 'Barangay San Isidro', which is a specific location within Rodriguez, but the first title does not specify a barangay, so it could plausibly refer to the same or overlapping works. There are no phase, package, or section markers, and the distance (1058m) is within the same river stretch. Innocent explanation is plausible but does not block publishing.
