Marty, welcome to the Creek and a BIG congrats on your upcoming project!
Tips/advice? Well, this list could get real long in a hurry!
Obviously, much depends on how deep your pockets are. I'm assuming it will be on a slab so, the radiant floor heat mentioned is GREAT! However, depending on your geographic location, if you need to heat AND cool, I would not discount going with a complete HVAC system to take care of both seasons! Operating windows (you
should have plenty of wall space even with a lot of windows!) to take care of the in-between temps/weather. Running water/sewer is the one thing I think I miss most in my shop! Wish I had it. For a shop that big, I would most definitely go with the largest available breaker panel, with at least, 200 amp service. The more you can separate circuits, the better off you will be. Try to separate out a room for your cyclone and compressor, in order to isolate the noise generated by either. And, speaking of "rooms", wall off an area for a finishing room, as well. Even if you can't afford to install an exhaust system right away, it would be a good idea to plan ahead for it. Also, I don't know what type of building it will be but, I would stay away from those huge overhead doors (the type like they have for machine sheds and such), as they are thieves when it comes to keeping your HVAC under control! Finally, plan your equipment placement carefully and do it often. What do I mean by "do it often"? Draw up a floor plan of where you
think equipment should live. Look at it daily and "walk" through the area over and over. Think of your work flow and walk it through again. Make changes and "walk" it through again and again. After several iterations of this, you'll start to get a good feel of where things should actually go. In a space that large, you have the advantage of being able to place things in permanent locations and not need mobile bases. You really only want to do that once!
Oh yeah...One more thing: You guys wouldn't be interested in adopting a 50 yr-old IT guy and aspiring woodworker, would you???
