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: 5 contracts awarded to 729 CONST INC FORMERLY 722 CONST INC by the same office started within 107 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 5 in the same municipality. It is possible these are separate projects planned together to address different flood-prone areas in Marikina City.
