A: First,
we will discuss the dimension of your carport or garage. Our
dimensions are Length x Width x Height and they are for the
roof/canopy only. The base of the carport or garage is
always 1 foot shorter that the roof/canopy length. For
example, a building that is 20'W x 31'L has a base dimension
of 20'W x 30'L.
For your concrete slab, we
recommend pouring the slab the exact width and length of
your building, unless you live in Florida. If you live in
Florida, we recommend pouring the slab 3/4" wider than
the exact dimension of the base and the exact length of the
base.
In all state except Florida,
for a 20'W x 31': building, the building base is 20'W x
30'L. The slab should be 20'W x 30'L
In Florida, the slab should
be 20' 3/4"W x 30'L..
