Design Mock-up vs Construction Mock-up

What are the main differences between the Design Mock-Up Program and the Construction Mock-ups? Essentially, the purpose of the design mock-ups are to inform the design. The construction mock-ups follow a specification, whereas in the case of the design mock-ups, the results of the trial will lead to a design specification.
