Maybe the girder isn’t on site.
The fixture thing it is!The orange cranes are beginning to go up. Good sign that a girder is going up.
I think because the dome footprint is more of a rectangle than a square so a level ring would be weaker. But don't quote me on that hahaIs there a structural purpose for the roller coaster look versus a level ring or is that aesthetic?
It might be because it will allow the roof to be higher. They can raise the cables higher with the additional height.Is there a structural purpose for the roller coaster look versus a level ring or is that aesthetic?
OttoMets said the black thing that was just put on the truss is designed to push the girders away from each other temporarily so there is room to get the golden girder in.Now the surveyors , engineers and project director can make a decision on what they see good to go or minor
adjustments.
That sounds like a scary meta-stable state to leave things in overnight. What happens if something comes up and you need to tear it all down ASAFP? I would keep everyone going on the clock until that final piece is in and the system is stable. Fire up the floodlights.OttoMets said the black thing that was just put on the truss is designed to push the girders away from each other temporarily so there is room to get the golden girder in.
His info has consistently been good. I believe him. They used the same device to bridge the gap and complete the truss on the north wall.
I believe it took a long time to get it properly attached and to get the spacing right so the last girder can go it. Given it is almost quitting time, I think it likely the crown truss will have to wait until tomorrow to get done. They can't even remove Skylar until the fixture is fully set in place.
Can you imagine the forces involved to move those girders even a quarter of an inch? Can you imagine the pressure on the person making these adjustments? What happens if they get too aggressive and crack one of the girders?
This has to be a scary time for everyone involved in the project. So close but so far.
