Tomcat - when you refer to a series of steel bars are they the arcs you talking about - the half hoops beneath the cable that provide height projecting up underneath the fabric that lets more light in and if so are they there for rigidity and support/strength in your opinion?
Yes. The earlier drawings of the new roof showed many what looked like small mini domes made of PTFE material. It wasn’t clear how they were getting that shape and I was a little confused about it.
It will be interesting to see how accurate that image is. The translucent portion seems more transparent than I thought it would be. I can make out the stands and field. I hope that is accurate.
I had a conversation with an engineer on the team some time ago, and if I remember right, the metal arcs are to provide some needed rigidity. The pull on the panels was putting too much stress on the seams and this is an engineering move to distribute the forces better and allow the domes to work together to put less stress on the seams. I may not be remembering that right, but that is what I remember.
Thanks njcuse. I remember you mentioned there was concern about the seams where the two parts of the roof meet.
Interesting. I haven't see anyone but Walt or Skylar put a spiral up before. This white crane has surprising skills.
Geiger’s roof design is a cable truss clad partially with tension membrane and rigid panels, covering the stadium’s 23,250 m² (250,000 ft²) area. The design features an external steel crown truss supported on the existing concrete ring-beam of the original roof and is designed to support more than 6,350,00 kg (7,000 tons) of snow while still providing natural daylighting inside the stadium.JMA Dome (formerly Carrier Dome) at Syracuse University | Geiger Engineers
The first and still the only covered stadium in New York State - is a 50,000-seat multipurpose domed stadium. Since its opening in 1980 it has served not only the university’s athletics department but also the campus and the greater Syracuse community through hosting a myriad of events.

What’s nice about the new crane doing the spirals, it allows Walt to prepare for the next girder.
I spoke too soon. They're still messing with it. There are 3 apparent choices:
)
The new roof is supposed to be, on average, 5 to 10 feet higher than the old one. But it is definitely going to be flatter. The hard perimeter portion of the new roof appears to be almost completely flat. And even the interior part made of PTFE looks to have much smaller curves that the old roof had.
I agree only the big ones can handle the girders. And I think it is likely you are right that the girder that has been sitting, waiting patiently in front of stadium control, is likely the next one to go up. Sure hope so.
I think that girder is next in line or will be the second one in this corner.
Real question here. If the roof is only 5-10 feet taller how will the wow factor huge jumbotron scoreboard hang down from it. Some punts almost hit speakers now?The new roof is supposed to be, on average, 5 to 10 feet higher than the old one. But it is definitely going to be flatter.

Still surprising how much square footage is lost though.
I remain curious what color or colors the new roof will be. This drawing apparently did not take colors into account...the crown truss is not even close to the brilliant white it turned out to be in real life. Pretty sure they can make the PTFE any color they want. Hoping it is not that dingy beige color.
Well, the wording I read was the new roof will be 5 to 10 feet higher on average.
I wonder if they will still need to attach the platforms. It looks like they can reach with the baskets on the zoom lifts.
