Construction Queue Question

[Binford]

Do constructions queues' build values spill over to the next item in the queue if the curent item doesnt use all of the resources?

For example, say you're building a ship which costs 2000 Min, 500 Org, and 500 Rad and your Space Yard has 3300,3300,3300 build rating. Does the unused 1300 of Minerals "spill over" into the next item or does it go wasted?

Thanks.
