Answer: The existing temp construction barrier wall provides noise and dust control to the CBI/DSR control room and should be maintained in place until most of the heavy construction is completed on the mod 4 side of the barrier wall. Barrier wall removal and final construction work in the CBI lab space will need to be coordinated with a two week look ahead schedule. Potential night work might be required during wall removal and final CBI space reconstruction.
