New here and love forum and mag.
I just bought an old camp which it turns out seems to have been an old school house built in 1800's from what I gathered in research. The floor beams which are all old logs squared on two sides are rotted beyond repair.These seem to be only holding up the floor.They rest on a cement wall around the perimeter of camp with a crawl space.The sill beams are notched to give room for the floor beams and it looks like the post are resting on the sill beams also.Being more of a metal worker I am not sure about this repair.Is it really possible that the floor is the only actual weight on these beams?If so it seems like over kill to have such large beams under it (approx 8x8). What is a good method for replacing these and should I use the same type lumber or go with some 2x lumber with tighter spacing?
The sill beams need to be replaced also I would think since being under there and doing the rest it would make sense to fix the whole perimeter.
I would appreciate any of your expert opinions as I see some here do this sort of thing all the time.
