Your phrase "we will be getting Bermuda grass sod laid down" implies to me that someone else is doing the work. If this is true, the only things you need to do are make sure you are picking a good installer and then watering enough.
Installing sod is kind of like painting where the preparation work is 90% of the job. However, in painting, bad prep work will show through the paint. Sod of course hides whatever it is laid over and looks glorious for awhile. A good installer will follow all the best practices, from prepping the soil the day before, having sod delivered the morning of and keeping it in the shade, staggering the joints, getting good root contact with the soil, etc. A subpar installer will potentially skip soil preparation, use old sod, or fail to make sure that each section is firmly in contact with the soil.
As far as watering, the usual mistake is not watering often enough and deep enough.
