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: 14 contracts awarded to 739 BUILDERS by the same office started within 62 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 5 in the same municipality. It is possible that these are separate flood control projects in different locations, each requiring its own contract.

Checked: October 22, 2026

This is a textbook C5 case: 14 contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO within 62 days, with 5 in the same municipality. The titles clearly refer to different flood control structures in different barangays/municipalities, as expected for C5. There is no evidence of a data artifact or false positive. The indicator is worth showing as it highlights a pattern of multiple near-threshold contracts clustered in time and location.
