You would need to clarify what you mean by surplus and deficit.
I'll start by saying that one of the arguments that's been made in the last decade is that the lack of major projects contributes to the lack of productivity growth. In other words, there's a deficit in terms of major projects.
Your question relates to the bottleneck and constraints associated with having a large number of major projects that we want to advance at the same time. The availability of labour, management skills and funding must be taken into account to advance so many projects at the same time.
