Example. A farm silo, which is a prefabricated glass lined structure, is intended to be permanently installed. The prefabricated glass lined structure is 70 feet high, 20 feet around, weighs 30 tons, and it is affixed to a concrete foundation weighing 60 tons, and it is set in the ground specifically for the purpose of supporting the silo. The assembly kit includes 105 steel sheets and 7,000 bolts. The silo can be removed without material damage to the realty or the unit itself at a cost of $7,000. In view of its massive size, the firm and permanent manner in which it is erected on a most substantial foundation, its purpose and function, the expense and size of the task and the difficulty of removing it, it is considered a structure and not machinery and equipment.
