top bars in isolated footing

[swelm]

i see the top bars in not requeried as per ACI but the deigner for the project said that it is seismic requeried

i doubt in that the number of the isolated footing is 1500 footing so we can safe much money

What section of ACI 318 precludes the use of top bars in footings...particularly if structural analysis dictates that they are warranted?
