CSA A277 “Procedure for Factory Certification of Prefabricated Buildings, Modules, and Panels”

National Building Code of Canada, Parts 3, 4, 5 & 6

CSA C22.1 Canadian Electrical Code, Part I, “Safety Standard for Electrical Installations”

Note 1: Unless otherwise specified, the Standards and Codes noted are the most current versions in effect.

Note 2: Various provinces and territories have amendments to the national building code, jurisdictions may require structures to comply with provincial/municipal codes in lieu of the national building codes, the local AHJ should be consulted on the applicable requirements.

Factory Built Engineered Modular Structures

All markings must be permanent and visible after installation.
1. QAI label with ‘C’ identifier (item 1097 – black lettering with silver background) is normally located in close proximity to the electrical panel.
QAI logo shown here:

2. The specification nameplate (item 1068, 8-1/2” x 14” size) is located in close proximity to the electrical panel and includes:
− Manufacturer’s Name and Address
− Date of Manufacture
− Model Serial Number or Product Code
− Foundation Type (Perimeter Foundation Wall or Piers)
− Floor live Load
− Specified Snow Load (1/50)
− Seismic Response S_a (0.2)

− Hourly Wind Pressure (1/50)
− Envelope Effective Thermal Resistance
− Windows/Doors/Skylights Thermal Characteristics
− Outside Design Temperature (Heal Loss or Heat Gain)
− Factory Installed Appliances
− Site Installed Components, Assemblies, and Systems
− Electrical Systems Voltage, Frequency, and Amperage

3. Other Markings as required by the relevant codes.

Note 3: The QAI label and specification nameplate are available from QAI and must be applied at the factory.

Engineered Modular Structures under Parts 3, 4, 5 and 6 of the National Building Code. These structures are intended to be used for a single Major Occupancy classified as Group A, Division 2 – Assembly. Structures included in this listing are used as portable classrooms manufactured in single or multiple modules in single storey configurations.

This certification does not cover completion of the spatial separation and the barrier-free access which is to be completed on site under permit. A qualified professional is required to design and validate exposing building faces and barrier-free design as per the requirements of the local authority having jurisdiction.

The design of each discipline: architectural, structural, mechanical, and electrical, requires review and approval by professionals registered in the province where the units are intended to be installed.

Structural:
Conventional Wood Frame Construction designed within the scope of Part 4 of NBC.

Electrical Ratings:
120/240V, 60Hz, 200A Max.

Heating:
Electrical baseboard heaters

Plumbing and Ventilation:
Plumbing systems are not included in this listing. Units may be equipped with energy recovery ventilator systems.

Gas Systems:
None

Fire Alarm and Sprinkler Systems:
None.

Notes:
Modular structures included in this listing are manufactured at a central facility and transported to the site. These modules must include provisions for on-site interconnections, connection to electrical power supply. QAI certification covers the construction of the modular structures including any factory installed electrical services, appliances, equipment and fixtures. QAI certification is intended to obviate the necessity of further inspection by the local regulatory authorities except for site connections to services or to other modules and for site installed features.
Site installation of products must be done according to manufacturer’s installation instructions and in compliance with the requirements set by the local authority having jurisdiction.
