How to get a pipe in the house. Note the second hole to the left of the pipe

The pipe in place on the inside, one each through the two holes on the outside

The rigid insulation in the basement. You'd be surprised how many times I've whacked my head harder then I'd like on that white plastic pipe coming out of the wall.

I've been plugging away at the drain and vent lines.

What surprised me was that in order to get certain lines into place in the floor joists, you have to continue your line of holes right out through the side of the house. What do you do if you've built a house out of concrete?

I've been enjoying the plumbing work; you basically have a pile of fittings and you dry-fit them together with lengths of PVC pipe and when everything is good and they are pitched the way you want them, you glue them all together with nasty smelling solvent glue.

I've also been continuing with the insulation of the basement in advance of our HRV unit being installed. (HRV stands for Heat Recovery Ventilation and is the mechanism that will supply us fresh air, since the house will be highly air-tight and super-insulated. Without this system there'd be no opportunity for fresh air to enter the house, or stale damp air to exit. More on this later.)

Anyway, the HRV unit will be installed soon in the back corner of the basement and I want to have the insulation in place so I'm not trying to fit it behind the unit after the fact. Putting up the insulation requires hanging sheet plastic from the sill , taping the overlap seams of plastic (the red tape in the photo), then cutting the boards of insulation to fit over the pink board coming up from under the slab. I then drill a pilot hole through a piece of strapping and the insulation into the concrete and finally screw a concrete screw to hold it in place.

The concrete crew was back at it again today and completed the installation of the wall forms and soon there after did the pour. The concrete came via a two-step process: concrete comes from typical delivery truck which then feeds into a pump truck which has an delivery arm that can extend up to 90 feet. This truck is run by a man who has a remote control unit strapped over his shoulders to direct both the arm of the truck as well as the flow of the concrete through the supply tube. Its amazing to see this efficient process in action.

All the while there is one guy walking along the forms directing the flow of the concrete into the forms while two guys follow behind with a vibrating machine that, well, vibrates the concrete to settle it way down in the forms.

Once the pour was complete, the crew then went around and firmed up the walls to make sure they were straight and true, leveled everything to their batten board, and then inserted the anchor bolts.

It was a big day, and exciting once again. So far so good. Tomorrow the forms come off and then were on to sealing and installing the perimeter drain.

Fun stuff.

Moving along...

Today the footing was poured. Its just amazing to see a drawing turned into reality. It's like, "Hey, I drew that!" and then the next thing you know, a hardworking crew of concrete guys comes along and makes it real. It seemed so distant in the design process and now here it is being laid out and poured as a matter of fact.

For example, I labored over whether we should include a radon vent in the house. The conventional wisdom around here says unless you are over bedrock you shouldn't have a problem. On the other hand, a good friend who had a house in Barre said they had their place tested and found very high levels of radon. I decided that we should go ahead and install the vent pipe in the event we ever find we need it. Today, when the crew was setting up the forms I ran down to town, grabbed some pvc pipe and laid it in place. The cost was negligible, the effort to place minimal, and now its there. It was hardly worth thinking about in the end and I'm glad we did it. I guess I'm just dwelling on the transition from concept to reality and how that transition happens.

Back to the process: The footing was poured today, and tomorrow, if weather allows, the forms go up for the walls. Every step is exciting, but I think seeing the wall forms going up is notable for its dramatic thrust into three dimensions - up from the 2D of the footings.
