Topics covered: Portal frame versus trussed systems, and where the crossover sits in practice Bay spacing decisions and their effect on purlin and cladding spans Bolted moment connections, bolt hole clearance and shim allowances for site tolerances Envelope detailing: cold bridging at eaves and ridge, penetration sealing, opening interfaces The minimum documentation package for fabrication release and inspection The note is written for project owners, contractors and consulting engineers who procure steel buildings from overseas fabricators, and is based on fabrication and export experience with industrial, logistics, cold storage and commercial steel structures.
