Would a precast concrete walling system be appropriate for a 12 storey apartment building?

Would a precast concrete walling system be appropriate for a 12 storey apartment building? Hi 3083936 There are huge advantages in using Tilt-up/Precast Concrete in multi storey constructions I dont go above 3-4 storeys, IMO above that incurs diminishing returns (profit) as a developer Advantages 1. It can be as much as 20% cheaper than Brick/Block construction (PC requires synergy along the entire supply chain) 2. Fast construction 3. Requires precision in design, engineering and execution 4. Right design saves on concrete forms 5. Optimal design saves money overall 6. Basically, Concrete is the cheapest building material in the world (<$200m3 AUS) Disadvantages 1. On Difficult sites Crane accessibility & cost 2. Services have to be prelayed 3. Design has to be modular 4. limitations on length and weight of panels 5. Limited scope for changes 6. Tilt-up requires on site casting beds (space) but no transport costs HTH Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs I couldn't attached the photo for some reason.
