Indicator C5 — Contract Splitting Pattern

AI-verified / Na-verify ng AI Data as of October 21, 2026

Contract Splitting Pattern

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 ST MATTHEW GEN CONTRACTOR & DEVELOPMENT CORP by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 5 in the same municipality. It is possible that these are separate flood control projects at different sites within the same municipality, each requiring its own contract.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

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, started on the same day, and all are in the same municipality. The titles name different sitios, rivers, banks, and barangays, which is expected for C5 (the rule is designed to catch clusters of near-threshold contracts in one municipality, not necessarily at the same site). There is no evidence of a data artifact.
