The Making of STTMP book also lists that the bridge docking port set that Spock Arrives in only costs $6000 and was the second cheapest set in the movie, behind Ilia's quarters which was a $3000 redress and reduction of Kirk's quarters.
EDIT: Sorry I should just share a photo of the book's listing of set costs.

The real shame is the hundreds of thousands of dollars the entire memory wall set cost but was ultimately cut from the film (which, from what I read, was a GOOD thing given the lackluster results from filming those scenes)
Also interesting is that the Rec Deck was quite a bit more expensive than the Bridge. I know the rec deck was
large, but it didn't seem overly complex. The bridge was much more intricate, detailed, and mechanically involved. Hmm.
I also don't know how Phase II costs are worked in. Perhaps the $205,000 they spent on the bridge was only the amount spent to get the existing Phase II bridge up to it's TMP standard.
