Tolerance, Concrete

Definition: the permitted deviation from a specified dimension, location, or quantity.- ACI Concrete Terminology


Tolerances are a means to establish permissible variation in dimension and location, giving both the designer and the contractor limits within which the work is to be performed. They are the means by which the designer conveys to the contractor the performance expectations upon which the design is based or that the project requires. Such specified tolerances should reflect design assumptions and project needs, being neither overly restrictive nor lenient.
