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 22IA0113 and 22IA0058 have near-identical descriptions about 72 m apart (funding year 2022; ₱9.60M, ₱9.32M). Worth checking whether they cover the same works. It is possible these are two segments of a single seawall project split into separate contracts.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects have identical titles with no distinguishing markers, are in the same barangay and municipality, funded in the same year, and are only 72 meters apart. The packet contains all necessary record IDs and URLs for public checking. Innocent explanations (such as a single long seawall split into two contracts) are plausible but do not negate the anomaly.
