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 BRENTMIN ROOFING ENT by the same office started within 14 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible that these are separate flood control projects in different barangays that happened to be procured at the same time.

Checked: October 22, 2026

This is a textbook C5 indicator: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO within 14 days, with three in the same municipality. The titles refer to different barangays/sections, which is expected for C5 and does not invalidate the indicator. There is no evidence of a data artifact.
