Hi @bhemphill
Pre-assembly has the potential to add a lot of value, no arguments there.
I think the argument that it could make a big or even significant impact on reducing embodied/upfront carbon is up for debate.
Generally speaking (and obviously project dependent), from what we’ve seen on our LCAs, carbon emissions relating to transportation (A4) and construction (A5) have a pretty small impact on the total carbon footprint.
At the end of the day, if we are trying to shave every piece of unnecessary carbon, then this is what we will have to do!
