AMMRL: Magnet (Varian R2D2) protection during blasting operations?

Hi.

A building construction firm is to start blasting operations just over the road from my lab.
In the lab I have an old and faithful cream-colored Varian 300 MHz egg-shaped magnet.
It sits on un-cushioned feet.
We have asked the construction people to use as small charges as possible but this may well not be enough.
I wondered if anyone has suggestions as to how I might protect the magnet.
I have been told that lifting it onto a rubber mat might help, but do not know what sort of mat that might be, thickness, material etc..
Also if such should be a possible solution - is it feasible to lift the magnet when at field without causing a quench?
I'd rather not take it down as it has been at field for almost 20 years and I have been warned that it may not come up again due to possible cracking of the epoxy.
Any suggestions - very gratefully received.
best regards
David
