A few more pictures of work in progress. Tried out the pier last night. L-bolts were positioned well in the pier, as I could catch Polaris about in the middle of my adjustability. I am a little disappointed with my southern view. I thought I had calculated 20 deg before the walls start to vignette my view, but obviously I was still thinking about my old LX200 fork mount and not GEM. I forgot how much lower the OTA rolls down. I'd like another 8-10" of height on the pier so maybe will consider putting on iOptron's mini-pier. I don't want to mess with concrete any more and risk messing up what I had. Its ok now, but it could be better. Just happened to want to view Saturn and Jupiter last night and I only saw them with less than half of my aperture.
The warm room size is small but actually is quite functional for one person. I will be able to have two large monitors side by side on my desk. Just enough room to roll back in the chair and get out from behind the desk. The view of scope from the chair is perfect.
I installed rubber horse matts in the telescope room, they are very heavy and lay down quite well - no need for adhesive. They did prove that my building is square
Lots of work to do yet. Next will be running electrical and then insulate and drywall the warm room. I have a full length glass door to install between the scope and warm room.
