Be sure that your metal buildings kit is manufactured by a company that will be available for customer support during assembly and afterwards, if needed. When the kit arrives, lay out the materials so that they correspond to the order of assembly (for easy access during construction) and confirm against the shipping invoice that all the required parts have been included with your metal buildings kit. Before you assemble your metal buildings kit you will need to lay a concrete foundation for support. (And make sure to conform to all local building codes when doing so. ) The easiest way to do so is to pour large square pads (large enough to support the full weight of the building) in the spots where you intend to place your steel columns.
