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 22CM0005 and 24CM0001 have near-identical descriptions about 1051 m apart (funding years 2022, 2024; ₱77.20M, ₱96.50M). Worth checking whether they cover the same works. The second project may be a continuation or expansion of the first, or may cover a different section of the river.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical except that one specifies a particular section (Sta.0+304 - Sta.0+788, Right Side) of the Kalaklan River, while the other refers to the river in general in Olongapo City. The second title could plausibly overlap or subsume the first, or represent a continuation or expansion, but it is not clearly marked as a different phase or section. The distance between the coordinates (1051 m) is within the same river corridor and does not rule out overlap. There are no distinguishing markers in the second title that would make it a clearly different work. Innocent explanations exist (e.g., the second project may be a continuation or cover a different section), but the overlap is sufficient to warrant public attention.
