That is some Piddlin poor enganearing to get those structures in with the process as it was. Would be asking WHO was the Enga of note that came up with that installation point and required such a low pick angle. My Arse would been sucking the seat cushion cover off or pinching multiple new buttonholes in it!!
I can't think of a project that I have done, where the engineers specifically came up with a procedure to install something. Usually the engineers design something, and hand it to the contractors and have them figure out installation. I have had engineers speak to how something could be rigged, what kind of ground pressure, load moments and rigging, but never one that came up with a install procedure.
On the tandem pick project- the liebherr had its best chart at 100' with only 114' of boom out. The more boom I put out, the less chart I have. The link belt had a better chart at 126' of boom than 114', but the chart fell off if more than 126' of boom was put out. Sometimes I have to study the boom configurations a little to find the best spot.
We are going to have to open up the wall a little higher on the job where I'm using my galion in the building. I'll have to put my 40 ton Rt boom through the wall from all outside, and I'm going to need some more boom up area. So the wall is going to have to be cut up higher.
