A template was made with the exact pitch and length of roof on these benches.
The end or edge of the roof is formed with a 2" x 12" and a 2" x 8" the outside edge of the roof will be 12 inches wide, the foam will be removed just in the front of the two #3 rebar's. You can see a black line there, this will be done before the Tridipanels are set in place.
The wire corner mesh will be fastened to the end of the panel, also before installing, also the foam will be removed from the lower or valley end of the Tridipanel. The wire mesh will be fastened to this end also prior to placing the Tridipanels on the roof forms, the rebar will then be installed.
Rod Hadrian Jr. lay's a 14' long rebar across form at the valley, this rebar was spaced every 6", this Tridipanel roof will cantilevers approximately fifteen feet out from glass line and this is why we have the additional rebar's, also this end of the roof is subject to hurricane force wind loads.

This view shows the form at the valley of the roof, the foam is removed from the Tridipanels, the concrete will be pumped in from the topside, the red duct tape covers the crack between the form lumber.
The rebar's are 14' feet long with seven feet extended in each direction, each Tridipanel is twelve feet in length, a total roof with twenty-four feet wide, the foam is removed 4" inches back from the exterior edge, the edge will also be poured completely around the roofs perimeter.
Two inches of Portland cement will be sprayed over the bottom sides of the Tridipanels with one and a half inches of Portland cement will be placed on the topside of the roofs.
Rod Jr. built this ramp to carry the roof panel up to the roof.
Installing Tridipanel roofs, all of the Tridipanels were installed in one day on roof #3.

Fastening down the Tridipanel, this roof length is approximately sixty feet long with the last fifteen feet free spanned out with no columns for support.
The last few Tridipanels have double #5 rebar installed, you can also see the foam removed where we will create a concrete beam here to increase the roof strength in this area.
A view from below, the rebar is extended seven feet in each direction from the valley.
