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 EGB CONST CORP FORMERLY: EGB CONST by the same office started within 83 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is common for flood control projects to be split across different barangays or river sections within a city for logistical or planning reasons.

Checked: October 22, 2026

This is a textbook C5 case: four contracts, same contractor and DEO, all within the specified cost band and time window, and all in the same municipality. The titles name different barangays and chainage, which is expected for C5 (the rule is about clusters of near-threshold contracts in one municipality, not about duplicate works). There is no data artifact or error.
