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: 5 contracts awarded to JCA CONST AND CONST SUPPLY by the same office started within 11 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 5 in the same municipality. It is possible that the projects were legitimately split to address different locations along the river within the municipality.

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 5 contracts, all just under the ₱50M threshold, were awarded to the same contractor by the same DEO within 11 days, all in the same municipality. The titles name different sitios and barangays, but for C5, this is expected and does not invalidate the indicator. There is no evidence of a data artifact.
