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: 4 contracts awarded to ASIAN PEARL CONST & DEVT CORP 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 separate segments or phases of a larger flood control program, each bid out as a distinct contract.

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, all started on the same day, and three are in the same municipality. The titles refer to similar types of flood control works, and the code has already confirmed the cost and timing criteria. There is no evidence of a data artifact or false positive.
