I need calcs for a pretty straight forward double pitch timber roof 15m x 4m. Would I need a complete set of drawings or can I just get a list of dimensions and fixing requirements to show the BCO? Can someone give a rough idea of teh cost for this please?
4x2 rafters at 400, ditto ceiling joists, 38x150 ridge board, 6x2 central binder, 3x3 hangers at 1200 M12 bolt and 36x3 washers top and bottom; 4x1 diagonal bracing either end, gable straps at 2m centres across 3 rafters and joists, nogged at strap positions, 4x2 wallplate with vertical straps* at 2m centres.
Joe - not on a Sunday, I make enough during the week, thanks .
*optional extra, if you read BRegs (see other thread)
