Just stumbled upon some great pictures of our Lincoln Center project. We were the erection engineers for this long span roof truss....

This included determining each pick, how to hang entire truss on existing wall, reinforcing of existing roof for construction loads, reinforcing existing retaining wall for the crane loads, rigging, full construction sequencing etc.

Final Building (Long Span Truss above building)...
In the foreground you can see the green roof that is hyperbolic. We were also involved in that project (Arup was EOR) back in 2009. We designed all the connections for that roof.
