Almost as soon as we had power back we also got the planning permission approved for our pool! The pool builder confirmed they would be starting the day after and off we go!
The day after, the pool project manager measured and spray painted the design onto the lawn. Because we had not seen a final design since the gas line marking and we knew things had to move a little, we asked him to get our approval before finalizing it. We're glad we did that because the design didn't quite work properly so we had him move the spa over 18 inches. Without that, there was no way the swim lane would have worked.
The marking itself is all very clever actually - the computer program they use plots fixed points that he can measure from other established points (corner of the house, corner of the yard, another previously marked point etc) and then the design is mostly fixed radii from those fixed points. It didn't take him too long - you get the idea from this pic:

The day after, the dig began:

That's the inaugural first scoop being taken :-)
And here they are a little later on having dug almost to final depth (we're going with 4 feet deep for the majority and 6 foot deep at the far end - our friends have told us the deep end gets little use so we minimized it).

Here I am with it all dug:
The day after the dig the rebar guys came and put reinforcing bars all around the pool. That was amazing to watch - they brought in all the bars and put them on the side of the pool and then did the whole pool in less than half a day. They have rolls of wire on their belts so they just pull in a bar, shape it as required and then wire it to the crossing bars as needed. They were very skillful.
There is rebar every 6 inches around the entire pool. Here's the finished job:

As you can see, the basic plumbing was also done that day. This is done so that they can pour the gunite next without waiting for final plumbing - this just fixes the position of the spa jets, skimmers and other inlets/outlets. You can just about see two pipes on the sunshelf next to the spa (to the upper right) - they will be bubblers to create some more noise and whatnot.

Today they're pouring gunite - in fact they're doing it right now... will post pics later!
