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 DJCM CONST CORP FORMERLY: DJCM CONST by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. These may be separate flood control structures at different sitios and rivers within the same municipality, 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 on the same day, and all in the same municipality. The titles show different sitios and rivers, but C5 expects projects to be at different sites within the same municipality. There is no data artifact or error, and the evidence is complete.
