what will you be using for the floor joists? 2x12" can span about 16' on 24" centers I've read which means maximum span would be about 32'. if one wants a wider building I guess expensive 14" i joists are the next step up? Just trying to figgure out how you are savign more than half? is that...
can you tell me who did the drawings/engineering for your structure? i'd like to hire them for my own similar building? or maybe you can send me your drawings for a fee please?
