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 ALPHA & OMEGA 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. These may be separate projects for different sections or banks of the river in the same area.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

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, started on the same day, and are all in the same municipality. The titles refer to different sitios and banks (Left Bank, Right Bank, Sitio Namalican 1, Sitio Namalican 2, Sitio Cabadocan), but for C5, the presence of different sitios or structure locations is expected and does not invalidate the indicator. There is no evidence of a data artifact.
