Ostanes Engineering delivers certified structural engineering solutions for custom and commercial sheds, engineered to the specific environmental and soil conditions prevalent in Brisbane. We check the supplied shed drawings and the site conditions to identify any extra design needed for your project.
Structural Engineering Challenges for Sheds in Brisbane
While Brisbane operates within Wind Region B, assessing site-specific wind actions (AS/NZS 1170.2, or AS 4055 where it applies) is essential for custom and commercial sheds, particularly on exposed sites. Kit shed suppliers may provide generic drawings, so we review the supplied drawings and the site conditions to identify any extra design needed, such as slab and footing design, anchorage of the portal frames (AS4100) and wind actions. Where reactive clay is present, the slab and footings are designed with soil movement in mind (AS2870).
Documentation for Your Approval Process in Brisbane
Ostanes Engineering provides structural documentation for your shed project to support the approval process under Brisbane City Council. Our deliverables include:
- Structural drawings
- Wind classification assessment for your site
- Portal frame design
- Concrete slab design to AS2870 where required
- Form 15 certification
Designed to Strict Australian Standards (AS)
All structural designs for custom and commercial sheds are certified against the National Construction Code (NCC) and relevant Australian Standards. Our designs adhere to:
- AS4055-2021 (Wind loads for housing) – wind classification for housing and similar structures where the standard applies; other sheds are assessed under AS/NZS 1170.2.
- AS4100-2020 (Steel structures) – Designing robust portal frames.
- AS2870-2011 (Residential slabs and footings) – Engineering heave-resistant, custom concrete slabs for reactive soils.
Servicing Brisbane and Surrounding Suburbs
Ostanes Engineering specialises in engineering custom structural steel sheds and heavy-duty concrete slabs for residential and commercial properties across Brisbane. Our intimate knowledge of local conditions allows for precise engineering solutions in areas including Rocklea, Geebung, and Acacia Ridge.
