Q: vendors for shielded rooms

["M. Woo" <m-woo@uiuc.edu>]

A researcher on campus is part of a project that needs to have 5
shielded rooms built for a research particle accelerator and related
activities at a national lab.  They have gotten an estimate for one of
the rooms from a company that deals primarily with building shielded
rooms for medical use, and he is pretty shocked at the price (> $1.1
million).  He would like to know of other vendors that might be able to
come in with a better price.  Quite honestly, as I've never been
directly involved with building these kinds of rooms, I don't know
whether the quoted price is reasonable or not.

I have quoted (with indicated deletions) information he sent to me
below.  Please e-mail me (address in .sig below) if you know of, or are,
such a vendor.  I will compile the information and pass it along to him,
so that he can contact the vendors himself.  (If anyone else is
interested, please let me know.  I'll be glad to e-mail or post to the
list, depending on # of responses.  You never know when you might need
to spec a shielded room for an accelerator, hm? :-) )

As always, thanks in advance for any info you can pass along!

Here are some specifics about ONE of the radiation enclosures that we
are trying to procure through [name of nat'l lab deleted].  The whole
package is for 5 such rooms with similar specs.  The contract would be
to fabricate the panels from steel-lead-steel sandwich, including
pre-wired electrical outlets etc, assemble them at [name of nat'l lab
deleted], and finally verify and fix their radiation-tightness.

Dimensions 5.5m long x 2.6m wide x 3.4m tall.
Wall thicknesses:
19mm front (2.6m)
50mm back (2.6m)
19mm sides (5.5m)
12mm roof

Fittings: pneumatic door 1m wide, 18" square 19mm window, 5 electrical
outlet strips, breaker box, some interlock hardware, exhaust fan and
some cable feedthroughs.

The price they ([name of vendor deleted]) are giving us is $225,000. 
I'd be interested if you can find any alternative potential vendors.
