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 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 3 in the same municipality. It is possible that each contract covers a distinct barangay as part of a planned multi-site flood control program.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

All three contracts are for similar works (flood control structure and improvement of waterways) in different barangays within the same municipality, awarded to the same contractor by the same DEO, started on the same day, and each just under the ₱50M threshold. The C5 rule expects projects to be in different sitios/barangays, so this is not a data artifact. The evidence is complete and titles are similar as required by the rule.
