Combination floating concrete slab and slab on wall.
Combination floating concrete slab and slab on wall.
(OP)
Hello all again
I am working on a project where an addition is being built to an existing industrial shop. This is a small industrial shop (60'x30') that is on a floating, thicken slab. The addition will double the size of the shop and will be on a similar floating slab, except for one end. At this wall they want a loading dock built so that the floor of the truck will be level to the floor of the slab. In order to do this the existing grade will have to be lowered and the slab will need a wall under it with a retaining wall on either side of the loading dock or maybe (depending on the grade, it does slope slighty down in this area) a retaining wall on one side of the dock and then the wall extending to the corner and around the corner until it is not necessary because of the level of grade (does that make sense).
All that detail may not be necessary, just the question have any of you had experience of a combo slab part floating, part on a frost wall. Is this something you would be comfortable with?
Thank you for any advise.

Arguing with an engineer is like wrestling with a pig in mud. After a while you realize that they like it

We are looking at the suspended slab suggestion. The concern raised by a local inspector is with part of the slab as a thickened slab and part on a wall how will the differential settling be addresses. The inspector is concerned with how this differential settling will effect the building itself. We are insulating the slab.
Thanks again

When you say "we are insulating the slab", what do you mean by this statement? What are the propertie of the soil, are we talking a highly reactive site or poor soil strength?

We are placing 2" rigid insulation on grade before the concrete is placed and also the same insulation will extend 4' from the footing to prevent frost from getting under the slab.
