Hey guys. So basically I've been locked out of my house and told that once all the rough ins are done (HVAC, plumbing and electrical), then we can do the walk through. At that time I'll also be allowed to put insulation in the walls of my kids bathroom and our laundry room (which is beside our master bedroom). Having said that, I will use OC R24 (as it's the cheapest solution to absorb the resonant frequencies of those walls) but it's 5 1/2" thick going in 2x4" walls. So I guess it will get a bit messy as I strip them thinner :-S
At that time, I will also be allowed to put my 20', 18' and 16' LVL stud into the basement for storage as I don't have windows in the basement to get them down there in the future. Talking with my lawyer, I may gain unlimited access at some point here though. We'll see. I'm honestly not too worried as I've found peace within myself with the project. Sadly, I'm starting to just realize that I'm getting screwed and I'll deal with it as it comes. I'm sick of losing sleep over it.
Other updates:
The builder and I had a verbal argument (which I recorded) on the phone regarding the garage in floor heating. I told them I wanted to put it in myself and then either have them pour the concrete on top or else just not have them pour it at all, and I would hire a company to do it. They basically said no, that they were contracted to do it and they are sick of me doing things myself. So, I got screwed. I can't afford the extra $10,000 they quoted me to rough in the lines (yes, just roughing in the lines. Not even hooking it up to a boiler or anything) and add a garage floor drain (which I thought they were doing already, but apparently they aren't). So, I guess I will have chilly garage/live room floors. Hopefully with proper heat in there, a bit of underlay, some laminate flooring, and a few throw rugs it will be decent enough. Fingers crossed. Here is a pic of the garage slab poured.

They also did some crazy crap with the front of our house roof line that is weird and the builder played it off by saying the architectural guideline people made them change it. Later on, I will request to see the email demanding the change and if they can't provide it, I will get my lawyer involved to cause some hell. I'm hoping to throw this builder to the wolves at the end of the build.
Regarding the HVAC worry, I've come up with 2 possible solutions in my head.
1. I requested that the HVAC supply be run on the studio room side of the hallway. Yes, still in the hallway, but have the supply on that side of the hallway. That way, I could maybe run the silencer sleeve right through the wall directly into the supply trunk.
2. Depending on if they used up my return floor joists and/or option 1 doesn't work for my supplies, I will hope and pray that there are enough free joist spaces (that have I-beams and not glued studs near them) above my rooms to run my duct work through and then cut holes through the I-beams and split my silencer boxes Y style to get the necessary cross sectional area. Then, from those, I can run other duct work through the joists to get to my registers. WAY harder job, but maybe a solution if need be. At least for whichever silencers I'm screwed on. The biggest thing that bums me out about this solution is the smaller spring gap between my inner and outer leaves that will exist. I mean, I'm already going to have to box in any duct work or plumbing that is run through the joists as it is. I am lucky that the joists are 14" deep, so I have quite a bit of room compared to friends houses that only have 9 or 11" I-beams!
As a side note, if anyone cares, I got a house gig at a casino venue. It's a beautiful room based off of a 1970's Los Angeles venue. 5.2 million dollar build for the room. The main bar is directly in front of the stage. The stage is actually really solid. I thought it was a solid concrete stage. It it around 7ft tall. I found out though that the stage is hollow underneath, but I think it's a concert slab. Probably could put about 8 grand worth of insulation under the stage, but it actually doesn't seem to be a problem thus far. I filled the drum riser with OC R24 and threw 2 bags worth of insulation in dropped ceilings in the corners furthest from the stage. I've never heard corners of a venue sound that good before. Like almost no bass build up. The PA is rented and twice too small. It was all hung before I got there. Hung at the 1/4 wavelength of the room. Flown subs with mid highs below the subs. They really need a cardiod mono sub cluster in the middle of the mid highs and to raise the mid highs up and add more boxes to get the throw better up in the balcony instead of using smaller delay fill versions of the mains. But hey, I'm just happy to have the job.
Anyway, the reason I wanted to share this is because there is a restaurant right behind the stage. There is a ton of bleed. I couldn't believe it. The wall separating the two spaces is a crappy steel stud 2x4" wall with ultralight 1/2" drywall and NO INSULATION in it! The stage is about 50 feet long and I can see about a 1/2" gap along the ceiling with light coming through from next door. I banged on the wall and figure the resonant frequency of the wall is around 400Hz. It's insane. The HVAC is huge (it's a large venue) and I can see it going right through the walls with no silencers on it. Classic -- a dumb architect making a room look beautiful but neglecting to take acoustic isolation into consideration. I've given all of the higher up people my advice and luckily, they realize they have to fix the problem. So, I was told tonight that the builders have a relationship with an "acoustical engineer" who they worked with in the past. He's coming to the venue tomorrow night during the show to check it out. I requested to meet the guy. I'm going to quiz him to see if he knows much. I hope he does. But I've studied up pretty hard so I will be sure to grind his gears a bit in front of the decision makers. I'll start throwing all of the terms and figures at him

I'll keep you posted on this as it should be somewhat entertaining!
Thanks for following. Once I get in the house and see what they've done with my joists, I'm sure I'll be going hard for a week on SketchUp re-designing my HVAC. So I'll update you with some pictures and plans of attack at that time. Let's just hope I can make it work, otherwise I've talked with my lawyer and I have grounds to either halt the build until I resolve the mechanical routing or else fire the builder and go from there. I really don't want it to come to that as the house will be amazing if it works out.
