Materials budget More than 40% of the materials budget is in the cost of electricity and it is difficult to predict the evolution of its cost over the next 10 years. The present cost of electricity at GSI is 11 ct/kWh of which 6 ct/kWh is directly for energy and the rest is for infrastructure fees. In the present estimate, it is assumed that the direct cost of electricity is doubled and the infrastructure cost is constant. This is consistent with the planning assumption at CERN for future energy cost. The total annual energy requirement of 250 GWh/year for running the facility is well defined so that even if the evolution of energy cost deviates from the planning assumption, this cost component is transparent.

Maintenance cost For maintenance costs, the estimate follows the directive of the German Ministry (AMEV directives). This requires 0.3% of the total construction cost for maintenance of buildings and 3% of investment cost of technical equipment. This is in line with the policy of depreciation at DESY for technical equipment although DESY has foreseen no budget for building maintenance. No upgrade costs or new projects are included.

Personnel Quite a detailed breakdown of the manpower required to operate and maintain the facility was given Whilst a few details could be challenged, for example some considered the number of FTE for radiation protection and safety to be too high whereas the number of shift operators is too low, the overall numbers are consistent with those required to run equivalent facilities at CERN and DESY.

Personnel (2) A consistency check could be made by calculating the average spend per FTE, dividing the materials budget of 96.7 M€ by the total FAIR estimate of 692 FTE (excluding the Research Division), giving 141 K€/FTE. This is remarkably close to the figures for maintenance, operation and consolidation in the two large CERN Departments with which it can best be compared. Document reference 5 5/21/2013
Conclusions The Panel agrees with the methodology used to estimate the operating budget of the FAIR Facility excluding research and computing. Document reference 6 5/21/2013
Conclusions The Panel agrees with the methodology used to estimate the operating budget of the FAIR Facility excluding research and computing. The biggest uncertainty in the materials budget is the cost of electricity supply. However the estimate of annual energy requirement is quite solid so this element is very transparent as real energy costs evolve. Document reference 7 5/21/2013
Conclusions (2) The estimates on maintenance costs for accelerators, technical infrastructures and buildings are in line with the policy at CERN and at DESY Although there could be some discussion of the distribution of staff, particularly between accelerator shift operation and radioprotection and safety, the total number of FTE scales favourably with CERN experience. The assumed average full cost per FTE may be carrying some hidden overheads so should be checked for double counting. Document reference 8 5/21/2013
