Thanks Hal - The people at West Penn were great. Very helpful. I will order their shielded waterproof audio cable for the run.
The contractor that is doing the trenching will install three 1.25" innerducts through the 4" PVC. We will then be the people pulling the fiber, 50-pair, and audio through two of them leaving one for the future. Will use OSP cable; knowing that water/elements will work their way into the pathway.
It works out to 1130' feet, with about 650' of that underground. The rest in running through their giant building to get to the data room. They are debating having the innerducts exposed in the inside runs vs running the 4" PVC all the way.
