2. North wall dismantling
• Works completed : • firefighting network interception
• chilled water disconnected barrack HNA 910
• mixed water station removed (north wall)
• old fan coil removed from barrack HNA 494
• raw water network interception (several places)
• Works to be scheduled before end of 2015 : • To be removed:
• ventilation ducts
• CW pipes & equipments
• drinking water loop
• To be rerouted: • compressed air loop
• demi water network
• raw water network
Specific care to asbestos !

3. Future design activities
• GAr extraction system : • pre-study in progress
• extraction flowrate to be frozen
• technical meeting scheduled on
friday 2015/08/07 regarding GAr system
GAr preliminary 3D model including extraction units & ducts

3. Future design activities
• Building general ventilation: • adding of 2 new ventilation units
• total flowrate: 210 000 m3/h
• total heating power: 2 440 kW
WP will be edited

3. Future design activities
• User requirements missing EN-CV needs technical data & requirements for designing the future extended networks as listed below:
• chilled water (for HVAC purposes)
• chilled water (for cooling down other some equipments)
• compressed air
• raw water
• demineralized water
• domestic water (hot and cold)
• fire fighting system
• gas extraction (other gases except GAr ?)
• ventilation for cryostat assembly clean room
• other… ?
