Indicator C5 — Contract Splitting Pattern

AI-verified / Na-verify ng AI Data as of October 21, 2026

Contract Splitting Pattern

Multiple similar contracts to the same contractor/DEO just under a threshold in a short window.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: 3 contracts awarded to C & F CONST & DEVELOPMENT CORP by the same office started within 56 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are separate phases or segments of a larger flood control project, each bid out individually.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

This is a C5 indicator, and the code has already confirmed that three contracts, each just under the ₱50M threshold, were awarded to the same contractor by the same DEO within 56 days, all in the same municipality. The titles refer to similar works in the same general area, and there is no evidence of a data artifact. C5 expects projects to be in different sections or stations within the same municipality, so the presence of different Sta. numbers does not invalidate the indicator.
