4. Marcello Maggi 7/12/2006 4 Status of RPC Commissioning  W+2 Completed (except horiz. Sectors)  W+1 Completed (except horiz. Sectors)  W0 Sector 4 and 5 to completion Sector Test are done before final cabling RPC BARREL

5. Marcello Maggi 7/12/2006 5 Status of RPC Commissioning  RE+3 pre-commissioned  RE+2 pre-commissioned  RE+1 pre-commissioned  RE-1/2 pre-commissioned Missing Front-End functional and read-out test and cooling test. Few gas leakages to be fix and understood Commissioning needs a clear resource allocation and commitments RPC ENDCAP
