By design, I'm making as few decisions as possible about equipment placement and the like until I get the shell up and can better visualize what should go where. I have a Bend-Pak low-rise scissor lift, and I've always liked installs where people have put these in a shallow pit so that they are flush with the floor. If you put a lid on them, they can blend right into the floor when not in use, or can be used as a heavy-duty adjustable table, as well as used as a regular lift.
With the slab going in in the next week or so, I had to make a decision on where to place the lift so we could incorporate the it into the slab with forms, provisions for power and hydraulics, etc. I considered multiple configurations, and an online friend was even nice enough to create these CAD drawings from the dimensions to show possible configurations, complete with cool scale Porsche 911s. The darker shaded areas would represent where the scissor lift pit would go.
Well, after much thought and consternation, I decided not to dig the pit, and to continue to use the scissor lift as a movable above-ground appliance. Given that a decision at this point would be literally set in stone (well, concrete) I decided the risk was too large that I might regret the location chosen before any other equipment had been installed or any shop work flow established. So I decided to just punt on this for now.
