2. Status
“Dfinitive” design unchanged since the Dubna Collaboration Meeting
“executive” design (blueprints and all that) to be done by the winning company
Fully funded by INFN
Safety specifications approved by LNGS
Technical specifications originally prepared for a single tender: Water Tank (INFN-GERDA budget) + Service Building & Superstructures (INFN-LNGS budget)
Does not include lock, clean-room,…
Need to have to separate tendering for lack of funding at LNGS in 2005 budget
Tender approval is by the INFN Council, after technical-administrative clearance by the central INFN offices
Lots of bureaucracy in Italy in the public sector
