The basics: The building is 5100 sqft. There are 3-5000 gallon tanks of either glycerol or veg oil, with a plan for a fourth. I have no idea what size the process tanks area, but there are two parallel production lines. There is no data on outside storage, but there has to be some. The specifier (I'm not using Engineer, because there is no evidence of engineer involvement) called for a 0.40 density over the whole building with 100 sqft sprinklers (even though he drew sprinklers at 144 sqft) To me, it sounds like they need some serious engineering in order to get this right. I'm not sure how far I want to get into it until someone "shows me the money" Any thoughts would be appreciated. Have a good weekend.
