I am about to sign a lease on a space and I am hoping to get a quick answer on an issue. As you all know liquid weighs a LOT and a 15 bbl (465 gallon) system sitting on a true 3x10 framing will not fly. I am thinking about supporting the beams with angle iron and lally columns. Now the details of the problem.
The beams run for about 14' (true 3x10") and sit on a granite fieldstone wall that looks to be in really good shape.
The weight: 7 15 bbl fermenters each with a 4'x4' footprint each weighing about 5000lbs full.
The area of the floor will be 17' x 15' area for the fermenters
The brew house will be a 15 x 8 area and will weigh about 10000 lbs full.
Also, I am in need of an engineer to hire and work the plans up for me in Boston.
Likely, there is local codes that must be met for your brewery. You should look in your local area for a food/beverage custom equipment engineer.
Or.. just purchase the equipment from a reputable supplier.
