[Dsg-rich] RICH assembly

[Marco Mirazita]

Dear Marc,
you are right, we decided some time ago to use man lifts instead of 
scaffolding. I will correct the work plan.
The procedure that I circulated covers only works on the RICH mechanics, 
the electronic panel test scheduled in the week 3 is simply a test that 
the panel mechanically fits inside the RICH box.
Procedures for the electronics tests will be developed by the RICH 
electronics group.
The mirrors will be assembled in a later stage. We will write the 
procedure, but most likely it is not going to require any tool that has 
not being used for the RICH assembly too.
However, in order to optimize the effort, both in terms of manpower and 
travel money, it is important that we get the proper authorizations to 
perform all the tasks planned in the 3 weeks as soon as possible.
Then, we will start to organize the trip of technicians and engineers 
from Italy.

Best regards,
Marco
