What documentation should a concrete subcontractor provide a builder?

Genuinely expected documentation includes proof of insurance, relevant licensing, compliance certificates for completed work, and where applicable, concrete strength test results or other quality verification specific to the project.

For commercial or larger residential projects, more formal documentation — safety management plans, detailed material specifications — may also be genuinely expected as part of the builder’s own compliance obligations.

A properly established subcontractor provides this documentation as standard practice, without needing to be repeatedly chased — worth taking note of if a subcontractor is consistently slow or reluctant to provide it.
