thanks for your time. I am not sure why engineer did control joint(thats the term they use on plan)on Base Slab of 16X24 mt, thick 300mm. that can be doable in one day or one pour.
control joint allow any movment in cocnrete. so is it any any voloumn replationship with tem. that governs location of control joint.
i agree with both, but i am tring to understand this issue technically in depth so i can prevent any further damange to public assest.
thanks,

To me, unless it is necessary for sound reasons, joint should be avoid/minimized in water retaining structures. If it couldn't be avoid, proper preparation for specific type of joint and good workmanship hold the key.
