Indicator C5 — Pattern Consistent with Contract Splitting

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

Pattern Consistent with Contract Splitting

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 ROTAFLEX CONST AND DEVELOPMENT CORP FORMERLY:ROTA FLEX CONST by the same office started within 9 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is possible these are separate phases or segments of a larger flood control program, each requiring its own contract.

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 9 days, and all in the same municipality. The titles refer to similar works (riverwall construction, different phases and barangays), but C5 expects projects to be at different sites within the same municipality. There is no data artifact or false positive here.
