Typical small building foundation in Maryland
Typical small building foundation in Maryland
(OP)
I am a structural engineer in Texas. Normally a foundation for a small building (15' x 50') would be a monolithic slab with a thickness of 6 inches and grade beams around the perimeter that are 12" wide by 18-24" deep. I have a project in Maryland where the frost line is shown as 29". If someone from the Maryland area is reading this could you tell me if a monolithic slab is typical for this type of construction or is the slab poured over a pre-poured foundation or some other type of construction?

15'x50' is a weird aspect ratio. Is this agricultural or a wash bay? I'd round that 29" to 30".

RE: Typical small building foundation in Maryland
The 29" was not the beam depth but the frost line shown in the specifications. My plan was to use a 6" slab with 12" x 36" beams turned down at the perimeter and 12" x 24" beams under the 4 timbers mentioned above. I also plan to specify a couple of contraction joints by cutting the slab about 1" deep along the short dimension and cutting every other rebar.
Any comments you have would be appreciated.
