vorhaben: intend to do sth
see also sentence #1661046, which has the same meaning.

Or all those "are you planning"-sentences, e.g. #3915070
(I translated quite a few yesterday)

So does that mean the sentence would become: "Are you already intending?" or is it something else? [sorry for late reply]

Yup! Something along these lines.
Personally I would place "already" at the end of the sentence but I'm not a native:
Are you intending to go already? (to express surprise)
