Just my 2 cents regarding getting electrical power to your bandsaw;
I think I'd suggest you simply install a power recepticle overhead and bring the power down rather than having an electrical recepticle mounted in the floor. Reason being every floor mounted recepticle I've ever seen EVENTUALLY is covered up by something or where a walkway is wanted - meaning it's turns out to be in a undesirable location. Overhead recepticles are ess apt to be in the way of changes in equipment layout, easier to modify or move, and will NEVER have any dirt swept into them or have fluids spilled or leaked into them. I'd also add a power lead down from the ceiling to the "island" workbench nearby.
Wayoff,
a) Are you planning on installing any floor drains or grating?
b) Will the floor have a slight slope towards the overhead doors?
c) Lastly, I don't know if you're planning that far ahead yet, but I'd suggest you consider to install a "whole house" exhaust fan that would pull stale/smelly air out of the work space and push it into your attic space and out the roof venting.
Keep up the excellent progress - Lookin' Good!
