Roofs consolidation : criteria Roofs consolidation : criteria

Categories of roofs repair: 1 - Sensitive equipment: roof leaks are ff i h f f i affecting the safety of equipment and/or the running of an accelerator; critical situation; immediate i t ti i i d intervention is required 2 - High frequency leaks: the roof is no more waterproof and leaks are more waterproof and leaks are detected very often; conditions will become critical if an intervention is not taken within a short time not taken within a short time

Conclusions

CERN infrastructure (surface and underground) is rapidly deteriorating trends are negative (i e roofs) => overall deteriorating, trends are negative (i.e. roofs) => overall consolidation planning on large scale is a major issue to be treated because of safety, legal, operational and economical reasons Consolidation costs are constantly rising due to the lack of Consolidation costs are constantly rising due to the lack of intervention (ex. Anti-carbonatation treatments) 2009 consolidation program is based on most urgent interventions k t d b t d di known today, but depending on:

• Budget (available today = 800 kCHF for all CERN (!))
• Boundary conditions during the approval of the program

y g pp p g (accelerator operation, weather conditions, etc.)

• Number of FTE assigned to perform the program

Increasing expectation for consolidation activities from CERN Increasing expectation for consolidation activities from CERN community, visible actions need to be done to avoid widespread feeling of frustration
