Why Flat Fee?
Most engineers charge hourly — you don't know the final cost until the invoice arrives. Our approach: $3,200+GST covers everything. Ask questions. Request amendments. Get council support. One price, no surprises.
What the flat fee covers
The $3,200+GST structural design fee is the same for every shed, in every state and territory, regardless of size, span, wind region or site complexity. A 100m² farm workshop and a 1,000m² machinery shed cost the same to engineer with us. The fee includes the full structural analysis, member sizing, wind-load design to AS/NZS 1170.2, connection and footing design, stamped drawings, specifications, and the Certificate of Compliance your council needs. Reasonable amendments after your review are included, and if council comes back with questions we respond at no extra charge.
What sits outside the fee
A few things are genuinely separate because they are paid to other parties, not to us: the council building-permit fee itself (paid to your council or private certifier), and a geotechnical soil report where one is required for footing design (carried out by a local geotechnical contractor). We don't lodge the permit on your behalf, but every document we produce is council-ready so your builder or certifier can submit without back-and-forth.
Do I need shop drawings as well?
Not always. Engineering is mandatory for a permit; shop drawings are optional. If you have an experienced fabricator, the engineering drawings are often enough. Shop drawings — a separate flat $3,200+GST — are worth it for owner-builders, less experienced fabricators, or more complex structures, because the fabrication-level detail removes guesswork and prevents costly errors on site.
Does my location change the price?
No. Whether your shed is in coastal cyclone Region D, the Wheatbelt, or suburban Melbourne, the fee is a flat $3,200+GST. Site conditions change the engineering — they never change the price.
