Questions 4mm and 12mm cladding (most probably 12mm) How much will removing the need for formwork reduce our costs/time (likely)? Manufacturing Considerations Do you think it is possible to assemble the rebar, mount onto base plate and weld up the cladding around it, before pouring the concrete? Is there a different way it could be manufactured? Is there a different design construction which may aid our costs? How might we simplify the manufacture? How might we arrange the rebar in the top shelf appropriately, allowing overlap with the longitudinal rebar? How might you suggest assembling in the grapple interface Official - Sensitive - Commercial

Studding details We are considering a set of studs along the base to increase corner strength Official - Sensitive - Commercial
