Message: [QUOTE="sutomcat, post: 3315656, member: 27"] In the video linked a page or two back, they used wooden platforms to stage the cables that comprised the back bone of the new roof. They laid the roof out on the floor and then raised it by pulling the cables from the wooden platforms up to the truss, to which they were permanently connected. It looks like they are going to use a similar process here. Though there is the small matter of removing the old roof first... They put the second, diagonal spiral up this morning for the girder added yesterday. Looks like the next step will be putting up a spiral vertically so they can put up the remaining box girder at Irving. Hope the spiral goes up today... [/QUOTE]
