Re: Clean power installation




HI Joe,

Most of these items should be included in the cost estimate of the Hall D
installation. They are not part of the scope of the civil construction,
although any mods to the civil to make it easier to install these at a
later stage is clearly very desirable. We do have some rough estimates in
the installation section based on previous experience, but these will be
useful for backup information to verify the early estimates.

I assume your proposal is simply to modify the existing civil panels so
that we can more easily install this additional equipment?

Thanks, Elton.
