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 MRB11 CONST CORP FORMERLY:MRB CONS by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are legitimate separate phases of a large project, each requiring its own contract.

This is a textbook C5 case: three contracts, same contractor and DEO, all started on the same day, each just under the ₱50M threshold, and all in the same municipality. The titles are highly similar, only differing by phase number, which is expected for this rule. The code has already confirmed the amounts and timing. There is no evidence of a data artifact.
