Abstract

The status of the construction and installation of CMS is reviewed. All big mechanical pieces have been assembled in the surface hall SX5 (except the 2 ^nd hadronic endcap calorimeter, HE+1, to be assembled this autumn). Full test of the magnet on the surface will start in March 2005. Waiting for the underground caverns to be ready, installation and commissioning of the hadron calorimeter and of the muon system has started in SX5. The assembly sequence followed by CMS (v33) is based on the completion of the full CMS detector, minus the staged items (ME4/1 and ME4/2, some RPC chambers at low angles, 50% DAQ online farm, 3 ^rd forward pixel disks), in time for physics in mid-2007.
