What is NOT a purpose of special inspections in concrete construction?

In the context of special inspections in concrete construction, assessing aesthetic aspects of concrete is not a primary purpose of these inspections. Special inspections are primarily focused on ensuring that the construction process complies with regulatory and safety requirements, as well as material specifications. Their goals typically align with verifying that structural integrity, material quality, and adherence to design documents are being maintained throughout the project.

The other options are integral to the purpose of special inspections. Collecting concrete samples for testing is vital to ensure the material meets strength and quality standards. Verifying temperature and moisture requirements is crucial for managing the curing process, impacting the durability and performance of the concrete. Additionally, comparing concrete to document requirements serves to confirm compliance with the approved plans and specifications, which is essential for structural safety and integrity. Therefore, option C stands out as the aspect that does not align with the primary objectives of special inspections in concrete construction.
