What concrete work do I need?

You will need concrete to install the building and there are a couple options for that. You can do a slab or you can do piers only to save some money up front and then you have the option of pouring a slab later. If you decide to go with piers only, most customers leave the dirt as is or pour a quick gravel floor inside the building.

Standard concrete pad

Base of a column and anchor bolts- the column is being temporarily braced while the building is being erected
