Christian, attached please find my comments on the RP, thanks.
Joe, nice job, I'm glad you took this on. You will see a thread running through my comments. I believe we need to address programs as well as projects, and with that, I think there are three types of multi-prime (I think the NYC model tends to get more play in the NE than elsewhere), and the third is really a program that is often called a project. I see it a lot in marine terminals, airports, and pharma campuses where there are eight or ten contractors, some of which are not working exactly on the same project, say the terminal, bridges, parking garage, maybe fuel depots, CUP, manufacturing facility, electrical substations, etc. Those are still multi-prime programs which might contain individual projects that are not part of the primary project but still have inter-project relationships, which is where the claims come from. That brings in other issues like an owner paying acceleration for a scope of work to a contractor whose standalone schedule does not show the scope to be critical, but once their schedule is integrated into the program schedule, it is critical. It's rare that planning is early enough to establish contract dates for primary critical path milestones for inter-project relationships so the individual contracts usually are bound only by the contact critical path. I hope my comments are clear on this. Thanks!
