Structural Design Auckland

LDE undertook the structural engineering design, drafting and Building Information Modelling (BIM) of the bespoke timber-framed residential dwelling. This unique marine boatshed architectural style consists of numerous boatsheds joined via integral flat walkways.

A specific engineering design was required for most of the dwelling since the geometry and style of timber construction exceeded the requirements of the NZS3604:2011 Timber-framed buildings standard.

The geotechnical investigation and analysis found that the building site was susceptible to liquefaction and exhibited TC2-like behaviour. To address the liquefaction issues, LDE designed a custom waffle slab. The foundation design was complex due to incorporating over-height foundations and polished exposed concrete finishes.

The building had numerous unique features, to list a few:

• A curved cylinder spiral custom steel staircase that was modelled using finite element techniques. Nodes were generated from parametric equations.
• Internal reflection pool entry reflection pool with an entry canopy walkway
• Greenheart hardwood custom trusses and cantilever posts
• Exposed cantilevered steel deck portal frames
• Suspended ceilings with variable height ‘boatwings’
