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 22OI0038 and 23OI0032 have near-identical descriptions about 6055 m apart (funding years 2022, 2023; ₱28.16M, ₱48.99M). Worth checking whether they cover the same works. It is possible that these are different segments or phases of flood control works along the same river, funded in different years.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only the word 'at' differing, and there are no distinguishing markers such as phase, package, section, or different place names. Both projects are for 'Construction of Flood Control Structure' at 'Zapote River, Las Piñas City', funded in consecutive years, and by the same contractor. The distance between the coordinates (6055 m) is well above the threshold for 'nearby', but the rule is about near-identical titles within the same municipality, not just proximity. There is no evidence of a data artifact or that these are clearly distinct works.
