Among other requirements, the manufacturer must supply drawings and documents sealed by a professional engineer licensed in the province or territory of the project site.
Due to the limited complexity and size of self-framed buildings, the manufacturer's drawings are frequently accepted for this purpose but the owner should be aware that this may not always be the case.
Many manufacturers provide minimum 24 gauge (nominal: 0.0239 inch; 0.61 mm) thick sheet steel in self-framing roof designs.
Many manufacturers provide minimum 24 gauge (nominal: 0.0239 inch; 0.61 mm) thick sheet steel in self-framing wall designs.
Diaphragm or racking strength of the wall and roof systems are dependent on issues such as the manufacturer's panel lap seam assembly and should be qualified by full-scale testing.
When a pre-engineered building is selected for a project, the architect accepts conditions inherent in the manufacturer's product offerings for aspects such as materials, colours, structural form, dimensional modularity, etc.
The principal differences between these two entities on a project are the limits of commercial obligation, professional responsibility and liability.
In the context described, the Architect and Engineer of Record are the designers of the building and bear ultimate responsibility for the performance of the completed work.
