Wind certificate or structural design: which do I need?
Builders, certifiers, designers and suppliers may use different wording. Start by identifying whether you need complete structural documentation, a standalone AS4055 site wind classification or a different engineering assessment.

Direct answer
Choose QuickFrame10 if a suitable Class 10 building needs structural drawings and design certification. Choose QuickWind if the only missing item is an AS4055 site wind classification certificate. Confirm the scope before ordering when the request says only “report” or “assessment”.
Complete Class 10 structural documentation
QuickFrame10 is the first pathway to check for a suitable Class 10 building that needs design, drawings, specifications and design certification. The new building has its own structural system and load path to the ground, but may adjoin or attach to an existing building without structurally relying on it. The service resolves the applicable wind basis as part of the structural design, so a separate QuickWind order is not normally needed for that scope.
Standalone AS4055 certificate
QuickWind provides an AS4055 Site Wind Classification Certificate for the nominated site. It is a fixed-fee online order pathway for suitable Class 1 and Class 10a projects. Member, connection, bracing, tie-down, slab and footing design are structural design deliverables provided through QuickFrame10 or a separate scope.
Builders, certifiers, designers and suppliers can upload the request or comment that prompted the certificate. Suppliers may use the wind classification when selecting windows, doors, garage doors, roof trusses, cladding or other components within their own design and certification scope.
Report, rating and assessment wording
These words are often used loosely. Ask the requesting party to confirm whether they need an AS4055 classification, AS/NZS 1170.2 wind actions, structural design, product certification or an assessment of existing work. Each is a different deliverable; a site wind classification certificate covers the AS4055 site wind class.
