Yes, everything below the first floor is concrete, then various other elements are concrete such as the elevator shaft. The rest of the structure is made from typical steel (where the loads require it) and then cold formed steel wall panels. CFS isn't the most common material but it's used with regularity in midrise construction.

Re the board that they're using: what sort of board is that and is it already waterproof? Thanks in advance
