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 SKYLINE CONST EQUIPMENT AND DEVELOPMENT CORP FORMERLY: EDDIE G GUILLEN BUILDERS INC by the same office started within 42 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. These may be separate flood control projects for different rivers or barangays within the same municipality, each requiring its own contract.

Prompt: v4

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, started within 42 days, and all in the same municipality. The titles name different rivers/barangays, but C5 expects this (the indicator is about multiple near-threshold contracts in one municipality, not duplicate works). All required record links and figures are present.
