And the framing is almost done. Waiting for roof trusses to be deliverred, everyone seems backed up, they are about eight days out.
Some of the questions answered.
Too late to run ducting in the floor, the slab was poured yesterday.
The ceilings are 10' I have an attic upstairs the whole length of the shop and it measures 7' high by around 9' wide. According to building code it is not habitable, but once the building is signed off, I have many plans waiting up there.
The lighting will be 8 ceiling mounted 4 tube LED fluorescent lights
What insulation I am not sure yet, the walls are 2 x 6.
Building will be air conditioned, including heating strips for the winter.
About the concrete expansion joints, they came from Builders First Source and were pretty inexpensive. They are galvanized steel rails, mounted with spikes or pegs in the base compaction prior to slab pouring and they align level with the grade as someone else mentioned in a post above. My previous house built 8 years ago had them in the garage floors and they worked out perfect.
Here are some pictures, one was left over and apologies it is full of mud.

Holes for pegs to secure them on the foundation to be poured
The fold over part is the screed and expansion joint
