Ostanes Engineering delivers certified structural solutions for knockdown rebuilds, meticulously engineered to address Brisbane’s specific soil conditions and foundational requirements. Our designs ensure structural integrity and compliance for your new build on existing land.
Structural Engineering Challenges for Knockdown Rebuilds in Brisbane
Knockdown rebuild projects in established Brisbane suburbs frequently encounter issues with uncompacted fill from former structures or demolished pools. Where fill is found, options such as controlled fill compaction (AS3798) or piered or suspended slab systems may be considered, depending on the site. This necessitates specialized engineering solutions, as further detailed in our residential structural engineering services. Where used, these systems aim to bypass disturbed soils by founding on suitable natural ground, as classified under AS2870.
Documentation for Your Approval Process in Brisbane
Ostanes Engineering provides the precise documentation you require for knockdown rebuilds under Brisbane City Council jurisdiction. Our deliverables include:
- Detailed structural drawings for all building elements.
- Site classification: taken from your soil report, supplied by you or by a separately engaged provider
- Earthworks and compaction specifications for sub-grade preparation.
- Form 15 certification for structural component conformity.
Designed to Strict Australian Standards (AS)
All structural designs for knockdown rebuilds are certified against the National Construction Code (NCC). Our engineering adheres to rigorous Australian Standards, specifically:
- AS2870-2011: Situs Classification and Foundations for Residential Slabs and Footings
- AS3798-2007: Guidelines on Earthworks for Commercial and Residential Developments
- AS3600-2018: Concrete Structures
- AS1684.2-2010: Residential Timber Framed Construction
