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 DEVEX INC / N B AVILA CONST by the same office started within 1 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is possible that the project was intentionally divided into phases for implementation or budgetary reasons.

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

This is a textbook C5 case: four contracts, same contractor and DEO, all started within 1 day, each just under the ₱50M threshold, and all in the same municipality. The titles are distinguished only by phase numbers, which is expected for a C5 indicator and does not invalidate the pattern. The evidence is complete and the public can check all records.
