Anyone have any suggestion for how to model post tension cables in Tally? We have an estimate of weight from our engineers, but I’m not sure if there’s a viable Tally entry for the PT cables.

[image] EPD for high-strength post tensioned tendons LCA Data & Tools I found the same lack of EPD’s and we are doubling the weight of the PT reinforcing as the embodied carbon coefficient for PT (Swedish) is about twice that of rebar. I believe Tally suggests this as wel…

Thanks Bob, for some reason this slipped past my search

Bob, if you can find it, can you share the resource that Tally offers that suggest this higher EC coefficient for PT? I feel like I have come across some rough Tally guidelines as well, but can no longer seem to find it. Thanks!

John, I am not sure what Tally currently says about this, as I no longer use Tally. There is an EPD on PT strands from Suncoast Post-Tension that you can compare against mild steel EPDs to justify this 2x multiple. We did alert Tally about this EPD. Suncoast PT EPD Bob

In the past, we’ve tried adding PT on the back end or doubled the quantity (as suggested by the CLF users in the past) and incorporated into our concrete reinforcement Tally definitions. There’s also a steel, cable definition you could try using, but you’d need to add an accessory material to the sl…

John, Tally also has a product that I believe is called “reinforcing rod” which has a similar GWP to PT strands. Bob
