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 23CC0124 and 23CC0141 have near-identical descriptions at the same coordinates (funding year 2023; ₱77.20M, ₱28.95M). Worth checking whether they cover the same works. The two contracts may cover different types of flood control structures at the same location.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects are at identical coordinates, funded in the same year, and the titles refer to the same barangay/spot (Matungao, Bulacan/Bulakan, Bulacan). There are no phase, package, section, or station markers, and no distinguishing place names. The only differences are in the type of structure (flood mitigation structures vs. revetment) and minor wording. This fits the rule's guidance for publishing: possible overlapping or duplicate works at the same site, with no clear marker that they are distinct. Innocent explanation: the two contracts may cover different types of flood control structures at the same location.
