Scope

1.1 GeneralThis Standard specifies requirements for materials and methods for the manufacture, transportation, and installation of architectural, structural, and specialty precast concrete products.
Note: This Standard should be specified for precast concrete elements used in segmental construction.

1.2 Shop drawings
This Standard specifies the requirements, in addition to those specified in CAN/CSA-A23.3, for precast concrete shop drawings.

1.3 Architectural precast concrete This Standard deals with the structural adequacy and architectural finishes of architectural precast concrete.

1.4 PrecedenceWhere this Standard states that the content of a clause is required to conform to a referenced Standard and to additional clauses of this Standard and there is a conflict between the referenced Standard and the requirements of this Standard, the requirements of this Standard take precedence.

1.5 TerminologyIn CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
