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: 6 contracts awarded to ROAD EDGE TRADING & DEVELOPMENT SERVICES by the same office started within 44 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are separate projects in different barangays as part of a larger flood control program.

This is a textbook C5 case: six contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 44 days, with three in the same municipality. The titles refer to similar types of flood control works in different barangays/municipalities, as expected for C5. There is no evidence of a data artifact or false positive. The packet is complete and the public text is accurate.
