Procedure for Factory Certification of Buildings
This is the fifth edition of CSA A277, Procedure for factory certification of buildings. It supersedes previous editions published in 2001, 1990, 1981, and 1972, under the title Procedure for Certification of Factory-Built Houses.
This Standard specifies the procedure for factory certification of manufactured, modular, and panelized buildings intended for residential, commercial, or semi-commercial use.
It specifies requirements for
(a) certification of the factory quality program;
(b) certification of the built product;
(c) auditing of the factory quality program; and
(d) in-factory inspection of the built product.
This Standard does not cover portions of buildings or services that are not completed in the factory. It also does not address the transport of buildings or their erection at the building site.
In 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; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability.
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.
