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 LLABAN CONST & SUPPLY FORMERLY: LLABAN CON by the same office started within 57 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 6 in the same municipality. It is possible that these are separate flood control segments in different locations, 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 57 days, and all in the same municipality. The code already confirmed the contracts meet the cost and timing thresholds. C5 expects the projects to be at different sitios/rivers/barangays, which is the case here (titles name different rivers, stations, and barangays). There is no data artifact or false positive; the indicator is valid and the evidence is complete.
