I'm in the process of buying a house and the surveyor has said that in the garage, there is a cast concrete beam which is holding up the front side of the house. This is resting on the external wall and a brick pillar. The pillar is built on the garage sub floor, which the surveyor has said has settled causing the bottom of the brick pillar to separate slightly and crack. He said the house hasn't moved, but the concrete beam is putting most of it's load on the external wall, rather than spreading it on the pillar like it should.

I'm trying the find a builder to quote for this work to see how much it would cost to rectify this and what would need doing but would be grateful for any advice.

The surveyor has said that it would need an area of the garage floor around the base of the pillar digging out, and then the base of the pillar rebuilt on the foundations of the house so that it is all supported.

Does this sound right and what would you say would be the cost for this type of work?

The following link shows some rough pictures of the garage and beam and the crack of the pillar identified by the surveyor. https://goo.gl/photos/DzuALmJauvAe2se68

Any advice welcome!

The surveyor is wrong. A brick pier can not settle in part or in isolation.

That joint might need pointing at the most.
 
Looking at the third picture there seems to be a crack between the floor and the wall on the left of the pillar. Thump the pillar with the flat of your hand, is it loose? It looks as thought the upper part of the pillar is hanging on the wall, which has not moved. Shame about the floor. Second thought, The wall and pillar are not leaning out are they?, that would produce a crack like that.
If the bits and pieces seem tight, I would just dig out the pointing to a depth of 20mm on one face at a time and re-point with a strong mix. After a few days, dig out a different face and repeat.
If your bits and pieces seem loose (?), then its a big job to underpin the pillar, especially as the floor seems to have dropped, you don't know what you will find under the concrete.
