When you say "below grade vault", do you mean something that's only
accessible through a manhole?
I haven't done this specifically, however if the vault does not have a
controlled environment, you could be dealing with massive headaches
related to dust/dirt contamination, moisture penetration, etc. I work in
a large-campus .edu environment, so I'm some of the headaches you're
probably trying to avoid. Also, be aware that access to the vault could
be an issue. There are OSHA regs related to what sort of training and
safety equipment someone who will be working in an underground vault must
I'm assuming that the fiber will be cross-connected to a new location
prior to the building being demolished.
Not knowing your outside plant or circumstances, would it be feasible to
fusion-splice a new tail onto the fiber that was going to the building
that's being demolished, or (ideally) pulling a new piece of fiber to the
new building, so you don't have to deal with potentially dodgy splices?
