The building is actually precast, please refer to my comment

I don't have good news for you.  you should visit www.concrete.com for
more info on this, and they have a concrete forum to ask questions,
but the reality is that concrete is not usually disassembled; it is
usually demolished and removed.  Reinforced concrete is almost
impossible to disassemble.

In other words, I'd wager your 5 quid that the only reasonable answer
is to destroy it with a loader, a wrecking ball, or with charges
(explosives).

(By the way, how is it "insitu" AND "precast"?  Insitu normally means
"concrete poured in place", and precast normally means "concrete
poured in a mold somewhere else, and then transported to the project
site"...)

You are quite right, it must have sounded confusing!  The building is
precast!
What I meant by disassemble is soft strip i.e. remove all the internal
finishes carpets etc.  and then remove the non-load bearing elements
and then the load bearing elemnts in the reverse sequence of the
construction.
This way I can recycle some of the materials which I might not be able
to do if I just blew it up or slammed a steel ball against it.

The problem is, I dont know how the precast reinforced concrete frame
is assembled, so i dont know how to reverse the order to demolish it. 
What cutting equipment can i use?

Hope i clarified things abit.

What does the building consist of.  Is it a multi story building in
the city centre, or is it a portal framed building on an isolated
site.  There is no single answer to your question.  The best thing to
do is consult a specialist demolishing company or a Structural
Engineer.  I am a Chartered Structural Engineer and I could not give
you advice until I saw the building in question.
