Post-tensioned Flat Plates

Does the ACI Code or BS standards allow tendons to be distributed equally both ways without the need to provide them in bands in at least one direction? <br>
From my reading of the ACI code and Concrete Society Technical Report NO. 25 which is based on BS standards, they seem to allow it.<br>
<br>
Can somebody clarify the above for me?<br>
Thanks<br>

ACI would allow the tendons to be uniformly distributed in both directions. The problem with doing that, however, is that it will make the placement of the tendons quite complicated. When tendons are banded in one direction, the banded tendons can be laid out first, and then the distributed tendons laid out over the band. When the tendons are arranged uniformly in both directions, they have to weave among each other.
