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: 4 contracts awarded to TCSC CORP / EFREN RAMIREZ CONST AND GEN SERVICES CORP by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is possible that these are legitimate separate flood control projects at different locations within the same municipality, all scheduled for implementation at the same time.

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started on the same day, and all in the same municipality. The titles name different sitios/barangays/sections, which is expected for C5 (the rule is designed to catch clusters of near-threshold contracts in one municipality, not duplicate works). There is no data artifact or error evident.
