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: 6 contracts awarded to CS CONST AND SUPPLY INC FORMERLY: CS CONST AND SUPPLY by the same office started within 91 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is common for flood control projects to be split across multiple sites within a municipality for logistical or engineering reasons.

Prompt: v4

Checked: October 22, 2026

This is a textbook C5 case: six contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, with three in the same municipality and all started within 91 days. The titles are similar but refer to different sitios/sections, which is expected for C5 (the rule is about clusters of near-threshold contracts in one municipality, not about duplicate works). There is no evidence of a data artifact.
