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 23OE0021 and 23OE0019 have near-identical descriptions about 204 m apart (funding year 2023; ₱96.45M, ₱93.82M). Worth checking whether they cover the same works. It is possible that these are two segments of the same project area, described differently in each contract.

How this was checked

publish · confidence 0.70

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both for 'Installation of Booster Pump along Estero dela Reina, (Phase II), Tondo, Manila', funded in the same year, by the same contractor, and only about 204 meters apart. The only differences in the titles are 'CM Recto Ave.' versus 'Barangay 9', which are not mutually exclusive locations and could refer to overlapping or adjacent areas along the same estero. There are no phase/package/lot or section/segment markers distinguishing them as separate works. This fits the rule's publish criteria for potentially overlapping or duplicate works.
