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
