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 22GK0009 and 24GK0129 have near-identical descriptions about 885 m apart (funding years 2022, 2024; ₱96.50M, ₱29.40M). Worth checking whether they cover the same works. This may be a legitimate continuation or expansion of the same flood control project in subsequent 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 a minor formatting difference ('Tuburan-Tomongtong' vs 'Tuburan - Tomongtong'), and both refer to the same set of barangays in the same municipality. There are no distinguishing markers such as different phases, packages, or additional place names. The projects are about 885 meters apart and funded in different years, which could indicate either a continuation or possible double funding for the same works. The evidence is complete and checkable.
