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 ROAD EDGE TRADING & DEVELOPMENT SERVICES by the same office started within 44 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 barangays and river sections, planned together for efficiency.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

This is a C5 indicator, and the code already confirmed that ≥3 contracts in the cluster are in the same municipality, with all contracts awarded to the same contractor and DEO, started within 44 days, and each contract amount just under the ₱50M threshold. The titles refer to different barangays and rivers, as expected for C5, and there is no evidence of a data artifact. The indicator is worth showing the public as a possible contract splitting pattern.
