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 JAGONBUILD CONST CORP FOR JAGON BUILDERS by the same office started within 1 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are separate projects planned together for efficiency or due to local infrastructure needs.

This is a textbook C5 case: four contracts, same contractor and DEO, all started within 1 day, each just under the ₱50M threshold, and three are in the same municipality. The titles are not identical but are similar enough (riverwall/road dike/box-culvert drainage in the same city), and the code already confirmed the cluster math. There is no evidence of a data artifact or that these are unrelated works in different places (the C3 marker logic does not apply to C5).
