Which publication is considered most useful for a Special Inspector?

ACI 318 is regarded as the most useful publication for a Special Inspector involved in reinforced concrete construction. This document, officially titled "Building Code Requirements for Structural Concrete," provides comprehensive guidelines and standards applicable to the design and construction of concrete structures. It covers essential topics such as material properties, structural design principles, and quality assurance procedures.

For a Special Inspector, ACI 318 serves as a critical reference because it outlines specific quality control measures and inspection criteria that must be adhered to during concrete construction. This includes provisions related to concrete mix designs, reinforcement detailing, and casting methods, ensuring that structures are built safely and in compliance with the established code requirements. The detailed specifications within ACI 318 equip inspectors with the knowledge needed to identify and address potential issues during the inspection process, making it an invaluable resource in their role.
