Starting a new Week

Scaffolding, Special scaffolding used on the inside of domes
I sort of got behind on posting last week. There was so much excitement building to getting the airform inflated that I sort of felt a letdown once it was up. So we went out and looked at the dome and went, it's up... Anyway, there have definitely been things happening out there.

They have built the scaffolding on the inside of hte domes to help them work up high. The picture shows it. What's cool about this is the way the wheels are set. Look closely and you'll notice that the wheels nearest the camera are facing like car wheels, ready to drive normally. The ones at the other end are facing 90° and thus parallel the outside edge of the dome and make it ready to spin inside the dome. I think it is a nifty way to set up scaffolding.

The other thing they began last week was the building of the window and door forms (called bucks, I think) to assist us in framing and mounting the windows. They have about half of the first floor windows done and all the doors. Monday they should be able to finish most of the rest, including the second story windows. This means that on Tuesday they should spray the polyurethane insulation. It will be a 3 inch thick coat all over the inside of the airform, other than where the windows and doors are. This will make it much darker inside.

Once it cures (overnight?) they will go back and install the rebar for the concrete and any electrical or plumbing that needs to be imbedded in the outside walls. Then comes the final 8 inch coat of concrete and the dome part is done and they move on to one of the other projects here on site. I think this should all happen this week, but it might lap over into Monday.
