walk-in freezer and cooler on existing slab

[Ben29]

I was asked to analyze an existing slab on grade for the installation of new walk-in coolers and/or walk-in freezers in various buildings.

The architect did not give me cut sheets for the walk-in units. But from my research I see that they are generally pretty light (30 - 40 psf). I also read from a previous thread that I should design for a LL = 275 psf,

My proposal is strictly for "analyzing the slab on grade to support the dead load + live load of the new units". But now I am wondering if I should take other factors into consideration as well?

Do I need to take special consideration of the temperature transfer? Or will the manufacturer typically provide floor insulation that goes above the slab?

Do I need to take special consideration for a walk-in freezer that is being installed on an existing loading dock slab?

You did not mention if the walk in cooler or freezer and the design temperature.I will suggest you to ask the recommended details of the manufacturer.

I would check the slab detail for temperature and frost build up besides structural check.

Pls look to the following thread ..

I cannot give you the formula for success, but I can give you the formula for failure..It is: Try to please everybody.

HTURKAK - Thank you!

The uniform load for a slab-on-grade is rarely a concern. The concerns in a freezer have to do with all the other details and consequences that go with -20 (or whatever) temps.

Are they coolers, or freezers? There's a big difference. If freezers, you have to isolate them and provide heating to keep the frost from going down.

I have both coolers and freezers. I have one scenario where the freezer will be outside. The rest of them will be installed indoors on an existing slab-on-grade.
Here is the instruction manual for the coolers/freezers:

Freezers, if located out of doors, should also be isolated to prevent frost from going into the soil.
