I have completed a rough but scaled SketchUp diagram of the proposed project, so do not need drawings. However do need timber sizes for columns and especially beams as the span is 7 metres. Beams are to be in treated H3 laminated pine and rafters are be in treated pine. The timber sizes shown in the SketchUp model are my guess at the sizes needed but that is all. Need you to do structural engineering calculations to confirm beam sizes, especially concerned about the size of timber (assumed to be laminated) as span is 7 metres.
Also need calculations done to establish recommended rafter size and separation and therefore number of rafters. On top of rafters will go battens for the steel sheeting to b...
