Hi, I plan to create an attic storage for my new single storey house and looking to hire an engineer to provide advice.
I have already done some preliminary work such as installed an aluminium attic ladder and screwed the following across bottom chords - a plywood sheet 2400x1200x17mm, MDF board 2420x2100x9mm and MDF board 2420x600x9mm. The plywod sheet is left behind under the roof by the builder. I have a colorbond roof and roof pitch is 25 degrees. Width of the house is 10800 plus eaves 450x2 so the bottom chords should be about 11700 long?
Any recommendation for an engineer who can do this job will be appreciated. Thanks
