How CSA standards are developed

8

Four principles governing CSA standards development• (a) inclusive, not exclusive participation (through committee

work and knowledge sharing)

• (b) respect for diverse interests (Balanced Metrix);

• (c) accountability; and

• (d) consensus achievement

• The CSA Public Review process provides opportunity for all stakeholders to comment on draft technical content in standards, prior to the final vote.

• CSA's balanced matrix approach ensures that relevant interests are included and contribute to standards work - and that no one single interest dominates the process.

• Achievement of consensus is a foundational principle - there are many requirements in the CSA standards development process that define and control how consensus is measured and achieved - consensus implies much more than a simple majority, but not necessarily unanimity.

CSA-A277-16 - Procedure for certification of prefabricated buildings, modules, and panels

Scope

This Standard specifies the procedure for certification of prefabricated buildings, and partially or fully enclosed modules and panels for buildings of any occupancy. It provides requirements for

a) certification of the factory quality program;

b) certification of the prefabricated product;

c) auditing of the factory quality program; and

d) in-factory inspection of the prefabricated product..

Scope is opened wide to Part 3 Buildings, Panels & Modules

Changes in CSA A277-16

1) The title of the standard has been changed to “Procedure for Certification of Prefabricated Buildings, Modules, and Panels”;

2) Introducing an explicit statement of application to modules and panels for buildings;

3) Introducing a new definition for “Factory” as a manufacturing facility that provides protection of construction materials, components, equipment, and products against adverse environmental effects during storage and fabrication;

4) Introducing a new definitions for “Prefabricated building”, “Prefabricated panel”, “Prefabricated module” and “Quality program”;

15

Changes in CSA A277-16 (Definitions)

16

Prefabricated building — a building partially or fully constructed in a factory. (Prefabricated buildings include manufactured homes designed and constructed according to the CSA Z240 MH Series, modular homes and other single- and multi-module buildings).

Prefabricated panel — an open or closed planar subassembly constructed in a factory and designed for use as an integral part of a building.

Prefabricated module — an open or closed non-planar subassembly constructed in a factory and designed for use as an integral part of a building.Note: Roof assemblies with trusses, sheathing and roofing, bathrooms, and kitchens are examples of prefabricated modules.

A prefabricated panel or module may be “open” (constructed such that all elements are visible), or “closed” (containing concealed parts or processes of manufacture that cannot be inspected at the site without disassembly, damage or destruction)


17


18

5) Clarifying the responsibilities of the transportation of buildings, modules and panels; introducing new requirements for the manufacturers to provide clear instructions on the transport, lifting, placement, installation procedures and a module or panel layout;

1.2

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, except as provided in Clause 7.5.1.

Note: Prefabricated buildings, modules, and panels should be designed to resist or accommodate loads and stresses imposed in transit and during placement. Loads and stresses imposed in transit will depend in part on the methods of transportation accepted by the transportation authority.


19

7.5.1 Instructions — General

The manufacturer shall provide, with each prefabricated building, module, or set of panels that are to be installed in the same manner, instructions that include, as applicable:a) transport, lifting, placement and installation procedures; andb) a module or panel layout.Note: Where multiple modules or panels are installed in a building, a single instruction document may be provided for all modules or panels.


6) Change in the terminology used to describe types of buildings;• A1 — Assembly occupancies intended for the production and viewing of the performing

arts;

• A2 — Assembly occupancies not elsewhere classified in Group A;

• A3 — Assembly occupancies of the arena type;

• A4 — Assembly occupancies in which the occupants are gathered in the open air

• B1 — Detention occupancies in which persons are under restraint or are incapable of

self-preservation because of security measures not under their control;

• B2 — Treatment occupancies;

• B3 — Care occupancies;

• C — Residential occupancies;

• D — Business and personal services occupancies;

• E — Mercantile occupancies;

• F1 — High-hazard industrial occupancies;

• F2 — Medium-hazard industrial occupancies; and

• F3 — Low-hazard industrial occupancies.

20


7) Reorganization of the technical requirement to reference first the codes and regulations that apply at the location where the building, module, or panel will be installed, followed by references to specific documents where such codes or regulations are not in force; (clause 4.1.1 & 4.1.2)

4.1.1 Requires prefabricated buildings, prefabricated modules, and prefabricated panels shall be designed and constructed to comply with those codes and regulations at the location where the building, module, or panel will be installed.

4.1.2 Where codes or other regulations are not in force at the installation location; prefabricated buildings, prefabricated modules, and prefabricated panels shall be designed and constructed to comply with NBCC, CEC Part I, NPC, NECB.

21


22

8) New reference to the National Energy Code for Buildings where there are no codes or regulations addressing energy efficiency in force at the installation location; (Clause 4.1.2)

9) Reference to the authorities having jurisdiction for requirements for professional involvement and stamped drawings; (Clause 4.2)

4.2 Administrative requirementsDesign, design review, and construction review shall be carried out by qualified persons, and stamped detail drawings and other documentation shall be provided as required by the regulations that apply at the location where the building is to be installed. (See Annex A.)AHJ may require in-factory review carried out by professionals who will carry out the necessary reviews at the appropriate stages in the process.


10) Clarification of the compliance marking requirements (labels or stamps) as they apply to prefabricated buildings, modules and panels;

7.4.1 Compliance marking

7.4.1.1 Building compliance marking

A permanent label identifying compliance with this CSA A277-16 Standard shall be applied to each prefabricated building in a location that will be visible on completion of the building. In the case of a multi-unit or multi-suite building, each unit or suite shall be marked.

7.4.1.2 Module and panel compliance marking

For prefabricated modules and panels that are not part of a certified prefabricated building, a permanent label or stamp identifying compliance with CSA A277-16 Standard shall be applied to each module or panel in a location that will be visible in order to confirm compliance at the installation site. (Compliance marking must be visible to verify compliance at the time the modules or panels are subject to site inspection by a building officials)

23


24


25

7.4.1 Compliance marking

7.4.1.3 Labels and stamps

Labels installed in accordance with Clauses 7.4.1.1 and 7.4.1.2 shall

a) comply with CSA C22.2 No. 0.15, Type B or C

i) for indoor use where installed in a location that will not be exposed to the exterior in the completed building; or

ii) for outdoor use where installed in a location that will be exposed to the exterior in the completed building;

b) be located only on surfaces identified by the label manufacturer as appropriate for the label; and

c) not be located on surfaces whose temperatures exceed the maximum specified by the manufacturer.Notes: 1- Stamps shall provide a performance level equivalent to that

required for labels.2- Type B/C — a permanent label that breaks up or indicates tampering when an attempt is made to remove the label.


26

11) Provision of options for providing specification sheets;

7.4.2.1 Provision of specification sheets

Specification sheets shall be provided as follows:

a) for prefabricated buildings:

i) be permanently affixed on the inside of each prefabricated building in a location that will be readily visible when the building is complete; and

ii) in the case of a multi-unit or multi-suite building, be affixed on the inside of each unit or suite in a location that will be readily visible when the building is complete;

b) for prefabricated modules that are not part of a prefabricated building:

i) be permanently affixed on the inside of the module or building in a location that will be readily visible in order to confirm compliance at the installation site; or

ii) be provided to the purchaser, where the specification sheet cannot be affixed as described in Item i);


27



Specification sheets shall be provided as follows:

c) for prefabricated panels that are not part of a

prefabricated building that is certified in accordance with

CSA A277-16 Standard and affixed with a specification

sheet in accordance with Item a):

i) be permanently affixed on the inside of the building in

a location that will be readily visible when the building

is complete; or

ii) be provided to the purchaser.


28



Notes:

1- Where multiple modules or panels are installed in a

building, a single specification sheet may be provided for all

modules or panels in the building.

2- Electronic access to the specification sheet information

may be acceptable to the builder, building official, purchaser

or other persons involved in construction review, at the time

of delivery and may expedite acceptance of delivery and site

approvals. This does not replace required hard copy to be

affixed to the building or module or provided to the

purchaser.


29

12) Reorganization of the specification sheet requirements

based on the properties or functions of components,

materials, services, or appliances installed in or provided

with the building, module, or panel; (i.e. Structural

modules or panels, exposure to unconditioned space or

ground, delivered with appliances, delivered with electrical

service installed, etc.)

13) New specification sheet requirements to identify the

date of manufacture, additional design loads, and energy

performance; and

14) Transfer of detailed information on instructions from

Annex A to the body of the Standard.


30

7.4.2.4 Specification sheet information for prefabricated buildings, modules and

panels designed for exposure to unconditioned space, ground, or the exterior;

7.4.2.4.1 The specification sheet shall provide the following information:

a) where the product complies with prescriptive requirements for thermal

performance

i) the effective thermal resistance of roof-ceiling, wall and floor assemblies,

or the thermal resistance of the insulation installed in roof-ceiling, wall and

floor assemblies;

ii) the overall thermal transmittance or energy rating for windows and doors;

iii) the overall thermal transmittance for skylights; and

b) whether the cladding assembly is constructed with a capillary break.

Note: The applicable technical requirements may specify required thermal

resistance as minimum effective thermal resistance or minimum thermal

resistance of the insulation. Where compliance is demonstrated by following a

performance path, the applicable requirements specify the documentation that

must be provided.


31

7.4.2.4 Specification sheet information for prefabricated buildings, modules and panels designed for exposure to unconditioned space, ground, or the exterior;

7.4.2.4.2 Where trade-offs have been used to establish required thermal resistance performance, the specification sheet shall identify

a) the assembly or assemblies where trade-offs have been made;

b) the areas affected in m2; and

c) the effective thermal resistances, nominal insulation thermal resistances or thermal transmittance as applicable for those areas.

Note: Due to permitted exceptions and tradeoffs, actual thermal resistance over any particular area of a roof-ceiling, wall, or floor assembly could be higher or lower than the minimum thermal resistance specified in prescriptive requirements. This can make it difficult to determine if the product complies with the requirements for a particular climate zone. Variations resulting from exceptions need not be identified on the specification sheet.


32

7.5 Instructions

7.5.1 Instructions — General
