BEARERS

175 x 75 This bearer was chosen due to it’s strength in the Y-Y direction as per moment of inertia. It requires the same number of footings as a larger bearer such as 200 x 75 would, yet it requires less material and is lighter and thus easier to work with.

• Chose not to use a double timber bearer as it requires more time to construct as well as creating additional issues with waterproofing and possible rotting between the bearers • Timber to be stored no less than 150mm clear of ground when delivered to site and covered to protect it from sun and rain • Joist off-cuts used for trimmers

Additional Specifications: • Timber end grain to be coated after being sawn using sealer such as petroleum jelly or Mobilcer-M Wax Emulsion to protect timber • Bolt holes to be drilled to bolt diameter +10% (allowance for shrinkage) • ‘Camo’ screws and tool to be used for even spacings as well as to prevent fastenings from being visible from the top surface of deck • All fixings to be stainless steel, Monel metal, hot dipped galvanised or mechanically plated

Sawn upper face timber used for greater long term weathering ability

3mm arris on all top corners as well as chamfered edges

Large surface area to relax on in the sun as well as this section next to the tree for shade on hot days Edge treatment covering ends of decking boards as well as framing deck

Main stairs compliant with rise and run specifications from NCC 2015 Building Code of Australia (Volume one commercial buildings) table D2.13

Longer full length decking used (can be purchased up to 6m) for efficiency and to reduce buckling between members due to expansion. Also to reduce waste and save time on fixing and joining.

Large platform stair to enable sitting/ lying to promote relaxation

Smaller pad footings to support stairs ‘U’ shape cut out to enable people to sit around edge as a group
