Under 910.04.02.02 Post-Tensioning Working Drawings, I suggest that is be made clear that the details for the ducts must include the appropriate friction and wobble coefficients to be used in the design calculations.
These are very important coefficients that can impact the engineer's tensioning calculations if the contractor changes suppliers or uses a different supplier from what was assumed during design.
The contractor should also be advised that the jacking forces specified in the Contract Documents is subject to change upon review of the working drawings.
