Message: [QUOTE="BMoreFan, post: 3441214, member: 7807"] Hi all! Long time follower of the board who's never posted but who's engineering brain has been extra interested in this roof project. I never thought I'd stare at a live stream with so little movement, for so long. Thanks to everyone for their efforts tracking down info on this! As I'm more of a visual person, I figured I'd share a couple sketches of what I've been seeing. Below is a cross section of what I believe one cable span will look like when all is done. The cables appear to have been lifted pretty close to their final position today as there isn't much slack left on the single cables. [ATTACH type="full"]183700[/ATTACH] As you can see, each span consists of 3 cables. A set of dual cables connecting at the crown truss on each side, and a single cable that connects close to where the old roof cables did. DoubleDee posted a pic that appears to show where this single cable connects to the old structure earlier this month. [ATTACH type="full"]183701[/ATTACH] The dual cables are really doing the heavy lifting here. Around the perimeter, the dual cables are on top, connected to the single cables below by what I've labeled as support wires in light blue on the sketch above. These support wires connect to the single cable below at those white wing things. As the cables move towards the center, the cables cross, so that the dual cables are on the bottom, and the single cable is on top. This is where the white vertical steel supports come into play, which I've drawn in magenta. On top of these, will go the steel arches, which I've shown in green (not even close to being drawn to scale, obviously). The actual roof materials will be connected at the level of the single cable/steel arches. This means the dual cables will actually be inside the building, below the roof towards the center of the roof, probably helping to explain the seemingly odd (read "not that tall") dimensions of the scoreboard. You can actually see this setup pretty clearly in the rendering. [ATTACH type="full"]183702[/ATTACH] Everything was lifted into place by the strand jacks on top of the crown truss, which aren't actually connected to the end of the dual cables, but farther down at what I've labeled the "connection point" to allow the "attachment point" to be connected to the crown truss. Below is a zoomed in sketch of the portion inside of the dotted orange circle on my sketch above which shows this. [ATTACH type="full"]183703[/ATTACH] You can actually see what I believe is this strand jack cable "connection point" in the pics posted by DoubleDee as well, but I've reached my attachment limit. Post #5,872, first pic at around 11 o'clock if you're interested. You'll see a metal fitting with the dual cable running through it, and a third cable connected to the middle. Also in the photo, on the far side of the stadium, you can see the slack toward the ends of the dual cables beyond where this connection is made allowing the cable to attach to the crown truss. Looking forward to watching the rest of the roof come into shape! [/QUOTE]
