And the vertical reinforcement which is in bot outer and inner face are we and our client in agreement about.<br /> Discussion is requiered horizontal reinforcement. Which for walls acording to ACI should be minimum 0.0020 of the gross concrete area. Now client insist that amount of vertical reinforcement should then be applied in both outer and inner layer. And I say the 0.0020 is for the whole section so when placed in inner and outer layers only 0.0010 times gross area is requiered in each face. Also then the same would apply for one way slabs only that there the ratio is 0.0018. Of course in both cases limitations for maximum rebar spacing.<br /> Am I correct? </p>
