Tomcat, NJCuse 97 and everyone who may be interested:
Finally got some information about I was calling the the "hoops" that support the fabric from the gentleman below the Engineer of Record at Geiger and how they are attached to the cable truss and when he expects the roof to be ready to go up and the "fabric arches" to be visible - just got his answer around 7:30 P.M.:
Dear Bill,
We received your email and hope we can answer your questions. As the Engineer of Record for the new roof Project, I am flattered at your interest in the project. As for your question, the steel tube arches that support the tensioned membrane (ptfe-coated fiberglass fabric) are referred to as the “fabric arches”. I am afraid there is no established technical name for these elements and like many components in a project like this, their name develops in the course of the project rather organically by the construction team. In this case, the name is appropriate.
The fabric arches are supported by the cable truss which is in turn supported by the new steel crown truss and the original concrete ring beam. The fabric arches are attached to the cable truss by the way of steel fabrications that bolt to the cable intersection clamps. The typical arch attachment is made via a machined ball & socket so as to “pin” the arch to the cable truss. You should be able to see these being attached on the web cam after the cable truss is pulled into place and jacked, which will be occurring over the next 4 to 5 weeks.
I hope this answered your questions. We appreciate your interest in the Project.
Thank you and Best Regards,
David M. Campbell P.E.

A considerate and informative gentleman. Don't know how well we may see these steel tube arches being installed sine there is no web cam except for Lawrinson Maybe tomcat could email Mr. Sala and ask again for the interior cam(s) unless the university feels they want to make this a big surprise for everyone and we'll say WOW!, when we see it. If tom doesn't want to then I will ask again but perhaps the lack of a cam has something to do with legal reasons, privacy restrictions, etc.
For me knowing that these "steel tube arches" are what they are called and that the name of them is developed as the job progresses be the construction team confirms NJCuse97's guess that there wasn't a name before the team got ahold of them. Thank you NJCuse97, tomcat and Mr. Campbell.
Tomcat, does his 4 - 5 week time frame agree with your estimate on the cable truss being pulled into place
and jacked?
