8. Fair Baseline Technical Report 2006 (FBTR) Version 2
Costs
Fair Baseline Technical Report 2006 (FBTR) Version 2
Building Cost FBTR 2006 is Million Euro
Cave 11,80 M€
Annex building 0,98 M€
The building cost in our Draft version as of now around 10.5 Million Euro
The cost optimizations are the following:
1) The cave floor is in one level
2) The sandwich walling is obsolete
3) 1 slab/floor opening for the crane instead of 2.
4) The new opening dimension is 6m x 10 m.

9. Thank you for your attention.
