Maybe they were dodging a pedestrian in the diagonalwalk.

A thing I've noticed recently is that for medium and small jobs, dump trucks don't deliver sand, gravel and dirt any more. It's delivered in big sacks.

It's much neater and contained with probably less waste. You don't walk past piles of sand or soil any more.

Whoever did this patch did a good job. The color is a bit off, but other than that, it's perfect. I don't think I could even come close to doing as nice a job. Just look at it.

just look at it! would you look at that.... just look at it.

It seems they are building a maze in the National Building Museum hall.

It's pretty cool looking. I first saw it several days ago, and went back recently to check on the progress.

It was hot out and I was just enjoying the air conditioning while absentmindedly watching the movement of the workers three floors below me. After a couple minutes, I started paying attention to what they were doing.

In the lower corner of this picture, you can see the cutting station where they are cutting the thin sheets of plywood to sheath the walls. In the upper right corner, you can see the guy who is installing the sheets of plywood.

They framed the walls all at once like you would normally do with construction, and are applying the skin of plywood to the studs.

There is normally a real benefit to doing all the framing at once followed by the wall sheathing. You can quickly lay out the walls and then just slap the sheathing on all at once. It's an economy of scale kind of thing. But I think it was a mistake with this maze.

Every time they cut a sheet, they have to work their way through the maze to get it to the guy who is hanging it. The stud bays are open in many of the walls, but because the walls in the middle are only 4 feet high, you can't step through them.

So it takes 3 guys to pass a cut sheet over to the guy who is going to hang it.

I think they would have been better off putting up the perimeter walls first and leaving the middle completely open with a clear path to the cutting station, much like painting a floor. I'm sure they are experts by now though and realize their mistake.

It's really cool looking though.

As they got closer to finishing they'd get jammed up in the middle. Better to lay out the pattern on the floor, marked with wall height. Then start raising walls from the center out, always having room to work.

I assume the fire inspector is looking the other way on this?

Why that's the finest matchstick grade luan an art budget can buy. :haha:

I was actually wondering why they bothered to frame 16 inches on center stud walls. There is no load to carry, and it's a temporary structure. I bet they could have done 24 inches and the walls still would have been sturdy enough.

If they get a lot of people in there and it backs up, they'll be leaning against the walls. There's no bending resistance strength in that stuff.

Have you seen this, glatt? From.

Ha! No. I'll have to go over there. It's about 15 minutes away.

I'll take a picture with my cellphone in the cellphone free zone.
