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 AKN CONST CORP by the same office started within 92 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. These projects may address different flood-prone areas within the city as part of a broader flood control program.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

This is a C5 indicator, and the code already confirmed that three contracts, each just under the ₱50M threshold, were awarded to the same contractor by the same DEO within 92 days, all in the same municipality. The titles refer to different creeks and locations within Parañaque City, but C5 is designed to flag clusters of near-threshold contracts in one municipality regardless of whether the works are at different sites. There is no evidence of a data artifact.
