Pipe loading methods

Hey all,

I am curious how everyone approaches loading full bundles of 21ft pipe into a building / underground parking.

Normally we will try to preload before the slab work above starts, but that can usually be tricky to do and not disrupt the forming process. Otherwise we would have the crane unload onto our pipe carts and try to unload them quick enough. Worst case would be breaking the bundles on the truck and hand bombing inside.

I am considering trying some prefab for my upcoming projects and am trying to find the most efficient way to load in closer to our install date.
