How would your answers to Exercises 6 and 7 change if the mechanical, electrical, and plumbing subcontractors were:

(A) Design-bid-build, with a separate designer working for the architect, or 

(B) Design-build, where the subcontractors performed their own design?

Data from Exercise 6

Assume a major subcontractor, such as mechanical or electrical or elevator or laboratory casework, is added to the precon team. Describe the process when and how they should be chosen, contracted, paid, and what their deliverables would include.

Data from Exercise 7

Building on Exercise 6, how does the precon process with a sub-contractor conclude? How are these situations handled and what are the implications if (A) the subcontractor is dismissed or, alternatively, (B) they are employed as a member of the construction team?
