Yes. Pre-engineered bolt-up buildings come with an engineer’s stamp , reviewed by an engineer before fabrication to confirm the design meets all building codes based on the project’s location. Always check your province’s code requirements and ask for CSA A660-certified kits with stamped engineering drawings. Weld-up systems, by contrast, can only be erected where building codes allow and where an engineer’s stamp is not required , an increasingly rare situation in Canadian municipalities.
