Can a builder request specific concrete strength testing?

Yes, genuinely — strength testing (typically via test cylinders taken at the time of the pour and tested at intervals, commonly 28 days) is a standard, available quality verification method, and a builder can reasonably request this for their project.

This is particularly relevant for larger or more structurally critical pours, where genuine, documented confirmation the concrete achieved its specified strength adds real, verifiable assurance beyond simply trusting the mix design.

A properly experienced concrete contractor should be genuinely familiar with arranging this testing as a standard part of quality assurance, not treat it as an unusual or difficult request.
