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 24OF0126 and 23OF0062 have near-identical descriptions about 220 m apart (funding years 2023, 2024; ₱95.34M, ₱96.50M). Worth checking whether they cover the same works. It is possible these are sequential or adjacent segments of a larger flood control project 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, both refer to construction of a flood structure along the same river and barangay, and there are no distinguishing markers such as phase, package, station, or different place names. The only difference is 'control' vs 'mitigation', which are not distinguishing in this context. The projects are about 220 meters apart and funded in consecutive years, which fits the rule's publish criteria for possible duplicate or overlapping works.
