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 BELL CONST 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 separate projects in different locations or phases within the same city, as is common for flood control works.

Prompt: v4

Checked: October 22, 2026

This is a C5 indicator, and the code has already confirmed that three contracts, each just under the ₱50M threshold, were awarded to the same contractor by the same DEO within 7 days, all in the same municipality. The titles refer to different sitios or phases, but C5 expects projects to be in different locations within the same municipality. There is no evidence of a data artifact, and the packet contains all necessary details for public review.
