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: 4 contracts awarded to ROCK-WBL CONST CORP FOR: ROCK-WBL CONST TRADING & SERVICES by the same office started within 7 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are legitimately separate packages for different stretches of riverbank, each bid out as a distinct contract.

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO within 7 days, with three in the same municipality. The titles are highly similar, and the code has already confirmed the cluster math and thresholds. C5 expects projects to be in different sitios or barangays, so the presence of different package numbers does not invalidate the indicator. All required record links and figures are present.
