Guide for Concrete Plant Inspection and Testing of Ready-Mixed Concrete

Description

This chapter recommends minimum requirements for inspection of the concrete plant when required by specifications or the owner. It is intended for use by specifiers, architects, engineers, owners, contractors, or other groups interested in monitoring the ready-mixed-concrete producers’ activities at the plant through the use of an independent inspection agency or in-house inspection organization. This chapterrecommends:1. Minimum qualifications of an inspector;

2. The minimum duties of an inspector; and

3. The type of reports that should be made. The scope and responsibility involved in plant inspection should be established in the contract documents, which should also define the relationships between the owner, concrete contractor, concrete supplier, and the inspector.

The plant inspector should be qualified by education, training, and experience to perform the minimum duties set forth in this guide. The inspector should have a technical understanding of the materials used to produce concrete along with the principles involved in concrete batching and should know the basic operating sequence of the concrete plant.

The inspector should provide evidence of his or her training and experience. ACI inspector or technician certifi-cations, Reinforced Concrete Special Inspector Certification(co-sponsored by ACI and various building code organiza-tions) or appropriate state agency certifications are accept-able evidence that the person has completed minimum training and examination requirements for specific areas of inspection and testing covered in this document. The inspector should also have and become familiar with the published standards referenced in this guide and with project specification requirements.
