1. 1 LHCb needs to space for upgrade activities and maintenance of the existing detector: detector R&D, detector module production, detector assembly, storage and large scale tests. Storage at P8 LHCb urgently needs decent storage space, preferably at P8  To protect tools and equipment which are currently degrading outside  To fulfill pending requests, LS1 and long term needs  To store the equipment needed for LHCb operation currently in Bldg 156  To store the DELPHI material from bldg 157, required for dismantling of the experiment. Estimate: 400 m 2, heated, cherry picker access, and crane. Assembly area for the LHCb upgrade, 900m 2. The building 156 shall be used for the assembly of sub-detectors for the upgrade and large scale tests for the upgrade installation. At present, the space is taken for storage of spare detector parts, handling and access equipment, and occasionally lent to the RD62 and Aegis experiments for their assembly. Lab in Meyrin site LHCb needs 2 small labs in Bldg 13/14 for upgrade R&D activities on new Sub-detectors. This has been already discussed and shall be in the pipeline.

4. 4 PX ‘material’ shaft LHCb workshop Visitor area (15% of the 70000 CERN visitors in 2011) Access control Control room

5. 5 Visitor area welcomed 15% of the 70000 visitors at CERN in 2011 The visitor area is shared with access/transport/recreational area. Major developments foreseen by the end of 2012.  The full VELO spare detector will be displayed. It will be the only place were Visitors will see a full LHC detector. Special display zone will be prepared by LHCb.  3D movie cinema room will be installed. The room will isolated from the noisy environment.  Short term LS1: The visitor flow is likely to be limited by the lack of space available  Long term >LS1: Control room will be freed (new building) to enlarge the visitor area

9. 9 Bldg 156 was used for LHCb detectors assembly Now it is used  For Support to LHCb operation (spare storage and repair lab)  for R&D LHCb Upgrade  Storage of delicate equipment's. upgrade activities LHCb needs to free space in bldg 156 for upgrade activities (R&D and detector assembly).

11. 11 Storage (Long term) LHCb urgently needs decent storage space, preferably at P8  To protect tools and equipment which are currently degrading outside  To fulfill pending requests, LS1 and long term needs  To free space in 156 for LHCb upgrade activities (R&D and assembly). Estimate: 400 m 2, heated, cherry picker access, and crane. Office (LS1) LHCb needs office space at P8, to host LHCb staff, users, and support group At least 5 offices (10p) from 11/2012 to 08/2014
