What is the status of the ACI 117 document in relation to specifications?

• A. The ACI 117 document is a narrative to the specification and not part of the specification itself
• B. It is the primary specification
• C. It is a test method
• D. It has been superseded by newer standards

Answer: (A)

ACI 117 acts as explanatory guidance that accompanies a project specification. It defines tolerances and how they are applied, but it isn’t the actual contract or the primary specification itself. For a project, the binding requirements come from the specification document (and any references it includes), with ACI 117 providing the detailed tolerancing context that the spec may cite or incorporate. It isn’t a test method, and while the standard can be updated, its role remains to explain and organize tolerances rather than to stand alone as the spec.
