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: 6 contracts awarded to BICOL GOLDROCK CONST CORP by the same office started within 6 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is possible these are separate flood control works in different barangays, each requiring its own contract.

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 a 6-day span, and four are in the same municipality. The titles are similar but name different barangays and sometimes different structure types (dike, revetment, seawall), which is expected for C5. The code already confirmed the cluster logic and thresholds. There is no evidence of a data artifact.
