Proper site location and preparation will help ensure a smooth installation and minimize settling over time and is the sole responsibility of the homeowner.
CAUTION: If your door/ramp is on a downward sloping side, your ramp may be too steep. Build up the ground on that side to decrease slope angle. 

DIY: In most situations site preparation can be done easily by the property owner. Either the site is nearly level or the homeowner can correct it by spreading a small amount of gravel. (See the directions below.) In situations where the grade is significantly out of level the homeowner can address it themselves or contract the work. If the property owner decides to put down a crushed stone pad, Shed Happens, Inc. recommends using 1 1/2″ of crushed stone (that being the stone size), making the pad 4-6 inches thick, and about 1-2 feet bigger than the shed. If the site is within the (10) ten inch limitation we can shim the building using concrete blocks.  CAUTION: Distances greater than ten (10) inches can make the building unstable and unsafe. The site must be leveled. 

If the building is to be constructed on concrete sono tubes, pressure treated 6”x6” posts, or a concrete slab, the work must be completed at least five (5) days prior to delivery to allow for the proper concrete curing time.  NOTE – If you plan to install concrete sono tubes we will provide you with a FOOT PRINT drawing and instructions to assist you with proper installation and alignment. 
The site must be clear of all debris including brush, stumps, animal waste and other impediments. Trees located in the general area must not have branches hanging over the site closer than thirteen (13) feet from the ground. Please allow for access of delivery truck to the site.
