I've been using the beehive plans available at your website and they have been very useful. I've been looking at some other plans though and find some variation in the depth. One book says:
"These 9 1/2" tall hive bodies are sometimes cut different depending on manufacturer, some are as short as 9 3/8" and all the way up to 9 5/8". It is better to cut them short because 9 5/8" leaves 1/2" bee space when used with standard frames that are 9 1/8". But most standard frames come out to be 9 1/6" leaving 9/16" bee space which is too much."
Why the variation in specifications? I've looked at the Dadant frames and they all are designed for boxes of your specifications.
