Just how much would a damped wall system cost for a 10K s/f project

This was taken from a Construction Blog dated June 22, 2007.  I doubt if anything has changed in 4 years, it more than likely costs more to do than what was originally published. 

To elaborate a bit further on QR (which btw, I think is a great product, just costly). The QR which is 5/8" thick is about $140/sheet. The QR-IIwhich is 1 3/8" thick is about $180/sheet.

Compare that with the price of two sheets of 4x8 5/8" drywall, along with $1/sq ft for GG. Add in the additional labor to do the 2nd sheet and you can see where the cost of the double drywall with GG is substantially cheaper than QR-II at $180/sheet. Now, if you were just doing a smaller job and didn't want to mess with the GG etc, then it can certainly be argued that QR might be easier/better to work with. But certainly not when you are doing a very large project.

ballpark estimates on a 10k Sq ft job.

QR -II - 1125 sheets = ~$202,500
No additional Labor

2250 sheets of drywall - ~$35,000
GG (120 buckets) - $25,000
Additional labor - $20,000
So, we're talking more than double for using QR vs having the crew do the same work twice. . . Not a pretty site on a large project.

So, you have to ask, is it worth the money and are you saving money?  Are You?
