When it rains, it doesn't pour

After a month of delay to fulfill the new topo requirement to the township, we finally got the inspection and could proceed to pour the basement.

Wouldn't you know it that this summer is getting  rain almost every other day?  A pour was scheduled on Wednesday, but was canceled the night before by the concrete company due to supply limitations.  They did manage to get some concrete to us on Thursday, but only a portion of the basement and the stair footing.  The concrete providers said they would come back next Tuesday to finish the rest of the pour.

 Here's the space between the elevator shaft and the workout room.  They poured the future theater and storage room.  A few observations.

• First, he spikes used to hold the temporary form board pierces the plastic, foam, and drives pretty deep into the substrate.  How annoying would it be if, in the future, I see water weeping up from these channels?
• Second, how does this joint affect the finish and quality of the slab considering this isn't going to be a single pour?  Granted, there will be a wall over this joint, but are they going to create an expansion cut here?
• Third, with the board in place, the rebar grid couldn't be pulled up into the slab so it's basically sitting at the bottom of the concrete.  I've read conflicting information on the efficacy and purpose of the light gauge grid.  Some people say it's just to help mitigate crumbling and hold the concrete together under cracked situations.  Others say that it will absorb some of the stressing energies, but only if it's elevated in the concrete.

Another shot of the storage/theater.  This is where the back wall of the theater will be.  I think the pipe on the left is the drain stack for above and the other is for the theater wetbar.

Here's the storage side.  I noticed some slight pooling of water around the pipe (that you can't see) that will be used for a sink rough in.  I hope they didn't think it was a drain and sloped to it.  The basement should slope towards the pipe you can see, which is the actual drain.

Here's the pour for the stair footing.  The pit was about 12-14" deep.  This footing will be used to support the weight all the way up to the second floor.

Another shot of the footing, looking at the workout room.

Here's the power wagon they used to distribute the concrete.  I didn't get to attend the pour, but my wife said the concrete truck drove down to the side walk out and aimed the chute into the power wagon.  They placed 4x8 boards down to drive over and dumped.  One or two other guys distributed and floated the floor.  That took place two days ago.  The concrete was hard enough for me to walk on, so that bodes well for future build time.
