My brother in law, who used to frame houses for a living and now is an estimator for a commercial construction company, did the work. I trust his judgement. There was a bit of work to be done building up and strengthening the roof system. It seems that the roof of this garage was built as fast as possible with most of the cross beams being added as an afterthought. The one truss we left intact in the control room is the one doing most of the work. The others were reinforced with gussets and rafter ties. It's a solid job.

Got another question for y'all:

I have a double wall between my tracking and control rooms...there is a 1" space between the two walls. I was planning on filling each wall with 8lb rock wool...but y'all are saying that it doesn't really matter what's inside my walls. I am wondering if this applies to my double wall? It seems to me that having more mass in each 2x4 wall would be better since the walls are decoupled from each other. I had bought enough rock wool to completely surround my tracking room...since every wall is either 1" from an exterior cinder block wall or 1" from another wall, it seems to be sufficiently decoupled...but, if it would be better for sound absorption to use the pink stuff, I'll do that instead...This stuff is fascinating!
