Permanent Engineered Modular Structures designed and built in single or multiple modules under Parts 3, 4, 5 and 6 of the QCC. These structures are intended to be used for a single Major Occupancy classified as: Group C – Residential.

Structures included in this listing typically include but are not limited to residential occupancy, and other buildings used for the sleeping accommodation such as houses, apartments, and dormitories. This listing does not include business/ commercial/ industrial units, assembly areas, detention centers, or any other occupancy that is not described in this listing.

For a full list of structures covered under this occupancy please refer to Notes to Part 3, A-3.1.2.1.(1) Major Occupancy Classification in the QCC.

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

Structural:
Conventional Wood or Steel Frame Construction designed within the scope of Part 4 of QCC. The steel building shall be manufactured by companies certified in accordance with the requirements of CSA A660 “Certification of Manufacturers of Steel Building Systems”. All welding to be done in a shop certified to the CSA W47.1 “Certification of Companies for Fusion Welding of Steel”.

Electrical Ratings:
Up to a maximum of 600V, 60Hz, 600A, single or 3-phase systems
Heating and Ventilation:
Primarily Electric Baseboard Heaters. Modules may be equipped with air conditioning (electric only).

Plumbing:
Conventional drainage and venting systems to a maximum of 240 hydraulic fixture units.

Gas Systems:
None

Sprinkler and Fire Alarm Systems:
This certification covers factory installed portions of the sprinkler and fire alarm systems. This certification does not cover completion of the sprinkler and fire alarm systems on site.

The design of these systems must be designed by a professional engineer registered in the province in which the building is intended to be installed. Installation and commissioning of these systems must be completed on site by qualified technicians as per the requirements of the local authority having jurisdiction.
