1. The HiLumi LHC Design Study is included in the High Luminosity LHC project and is partly funded by the European Commission within the Framework Programme 7 Capacities Specific Programme, Grant Agreement 284404. Review of HL-LHC surface buildings Technical Infrastructure EN-EL N. Dos Santos WP17.2 17 th September 2015

2. 2 General Statements Lighting, power sockets and minor heating (that not considered by EN-CV) of all surface buildings (listed in the subsequent slide) have been taken into consideration on general services load balance. Information provided by EN-HE considering total crane/lift power need has also been taken into account. The current total power calculated considers all of the above (to the extent of detail possible at this time). Wall fixing services (cables trays, ventilation ducts, piping, etc) should be considered to define the span between building columns Space requirement: cable trays (700 mm large x 300 mm high) should be reserved in inside building perimeter General services switchboard (1 m large x 2 m high) Cables passages to be considered between technical gallery and surface/underg. Buildings Access to roof lighting and others services should be possible from cranes walkway Concrete slab need for most of surface building (as prensent is last meeting) HL-LHC - 17.09.2015 - N.
