Ya it's a 1.5 million dollar temporary shop lol. The 30 million dollar permanent shop wont be done till 2019 so this is home for most of the mobile stuff. The big drills and shovels will likely never leave the pit though.
The floor is rig matting welded together. I believe it's fir or maybe oak rough cut 4x6 timbers stacked a foot deep. Holds up just fine for now. Will see what happens when they start walking D10's and 475 Komatsu Dozers over it.....
Well it's sure beats being outside
