Some great pics on JPW Facebook page tonight.
A good look at some of the components we’ve been talking about the few days.
Awesome pictures. This is what we have been waiting for. Even if Pete Sala remains silent until the project is complete, at least now we can see a little about how things are being done.
You can see a lot here. The white things with wings on the sides of the end zone are prominent in photo one. They are being held in place with temporary cables right now until the roof cables are pulled up over the crown truss to give the roof its dome shape. You can see holes that will be used later on these pieces to help support the hard shell part of the roof.
You can see the roof cables with their connectors, and how they have been brought almost all the way to the top of the crown truss. You can see the strand jacks, which are clearly installed on top of the truss and doing the heavy lifting work.
I doubt they lift the net any further as things stand now. I think they need to install a second set of cables to hold the cable net in place, this time attaching at the diamond that marks the border between the hard shell part of the roof and the PTFE part of the roof.
Once they do that, they can disconnect the original cables used to lift the cable net up near the crown truss, which will free the ends of the roof cables so they can be connected securely to the white tension ring. That will have to be done slowly, one column at a time,
Once that is done, they can pull the net up higher, to where it needs to be long term. I think the honeycomb of cables that will support the PTFE portion of the roof will be flat, with the cables pulled taut. You can see where these cables intersect that there is a square shaped junction box that keeps the cables square to each other. You can see where workers are installed a cap on these squares, which will surely hold the vertical supports that will support the arcs. The vertical supports will have different lengths to give PTFE part of the roof its dome shape.
I think you can see a couple of the vertical supports in the air, held by cranes. I assume those are what the white steel tubes are up there.
No strand jacks in the end zone. The cables there are only one cable of steel as well (the ones getting pulled up by the strand jack have double cables). The original roof only had 14 roof cables. Looks like they have cables for all the columns now.
Note that there are no cables for the lightning rod columns. Looks like they will install cables from one end to the other later. I think there is also one to be added that will go from end to end from south to north.
