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 23IK0021 and 22IK0032 have near-identical descriptions about 470 m apart (funding years 2022, 2023; ₱110.97M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers additional protection works at the same site.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to 'Construction of Flood Control Structure' at 'Golden Bridge San Juanico-Basey-Sohoton Road, Basey, Samar', and there are no distinguishing markers such as phase, package, section, or different place names. The only differences are minor wording variations and the addition of 'Protection works' in one title, which does not clearly indicate a different scope. The projects are about 470 meters apart, which is within the same road/bridge area, and funded in consecutive years. This fits the rule's publish criteria for possible duplicate or overlapping works.
