We might follow your lead and request another CSC. I'm not sure if we can get away just communicating with our SS throughout construction.
dont know if its the same for you guys, but i had a diff person during contract stage, now that we are in construction stage, we have another person or a " building support co-ordinator " as well as a SS
so far the BSC has been pretty accommodating but im not sure on SS, i've had no contact from him this week at all, after being given the run atound last week
