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: 3 contracts awarded to J SIMEON CONST by the same office started within 88 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are separate projects for different sections or esteros within the same city, planned and bid out at the same time.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

All three contracts are for bank improvement (steel sheet pile) works in the City of Manila, awarded to the same contractor by the same DEO, started within 88 days, and each just under the ₱50M threshold. The titles indicate two contracts are for adjacent or sequential sections along Estero de Magdalena, and one is for Estero de Vitas, but all are within the same municipality. The C5 rule expects projects to be at different sites within the same municipality, so this is not a false positive or data artifact.
