I decided to go for the 8x24 panel in a commercial application I am doing. I would like any feedback on comalong system for drawing the panels together. Does any one have any great shoring or brace systems for handling these jobs? What tricks for glue applications for splines? Any preferance for fastners? (nails,stapples,screws). With crane set what would be a bench mark of time for setting a panel? Does using a leddger for second story with glueing and screwing work with just a backing band? And for the jackpot question
what is your preferred way of rigging a panel? (specific attachment method, location of straps,chains or wirE?
By the way it seems they do this diffrently all around the world. So lets figure out tha american way.

On jumbo panels use a crane, pettibone or forklift for the walls. They will position the panel just fine. You can use pick points by finding the balance point for the pictch you need and poke hole thru the outside skin, putting a 1x4 or osb strip with screws above the hole, insert a pick of some sort and lift the panel into place. For walls use two pick point on one side of the wall and at least one on the other side to get a straight lift. Glue the female side of the spline . I prefer staples at spline locations and fly-by corners for big panels. I aways use screws at roof and roof to wall. Ledgers should be engineered or nailed into infill in the panels. I would not trust glue and screws for a large load. You can make the pick points from crow bars with a welded loop for attachments.

In regards to rigging Jumbos, I have forged large panel hooks which pierce the outside skin. the flared tip or point distributes the load and allows us to safely pick a 1000+ pound panel. the hooks are strapped with 30' webbing in pairs. A buckle on each pair allows short lining adjustments for accomodating roof pitches. The perimeter of the panel must remain unobstructed for easy joining of panels.(this is why we like the hooks so much)
Once on the roof, we use ratchet straps to coax the panel into position. With good QC and cutting, you may not need to strap it at all. Worse case panels for us may require as many as three straps along with a few expletives for good measure. The punctures left by the hooks allow for strapping to pull in a variety of directions.
The number of lifts will typically determine our quoted price as opposed to a square foot per day estimate. I'm happy with my crew of three completing 20 lifts in an 8 hr day. If the panels are 4x16 versus 9x24 the squre footage installed per day can vary greatly.(one of the three is my crane operator who also doubles as the ground man doing panel prep and rigging) If site fabrication is required, add a cut-man and figure on setting half as many panels.
We set up compressor run nail guns for the ground crew, and work strickly wireless up top with paslode nail guns and cordless screw guns for running in the Oly screws. Quality calk guns for both crews and I agree that the neatest rule of thumb you can adhere to is always calk the female side.
We're currently experimenting with some self adhearing joint tapes that will not only give a superior joint but also get us off a watertight roof without having to felt!
As far as a crane goes, we use a 15 ton 115' boom truck with an operator who uses a wireless remote to allow him to be were he can help.(like on the roof instead of out of site in the truck) Try the sign industry for this type of rig you may get lucky
Best of luck, Al
