I actually managed to get a call from the Site Supervisor today with an update on what's going on - we already have walls - yikes.
Yes, the frame has been delivered on-site, and they're already putting it up. He expects a large portion of the walls to be up by the end of today; Monday the roof and trusses will be delivered and they will all be up by Wednesday afternoon with the frame complete!
After that it will be the tiles, fascia and gutters - he expects those to be complete by Friday week (30th). They don't waste any time after that and get the insulation in and then the Hebel over top.
I'll drop by on Saturday or Sunday to get some photos.
