This is not a lack of confidence. This is noting that several ideas have been shot down by others who should know; or others who do this for a living don't know how to do it; or (as it seems) the general contractor knows someone who says they can do it but he doesn't trust them to get it right.
I think the biggest issue is just the unique construction. Building with concrete is not very common in the US, so no one knows how to do it.
Building with concrete is very common in many other parts of the world, but they generally aren't trying to produce a finish quality surface with it and probably aren't dealing with things like central vac, shade pockets, etc.
