Which professional do I need to review a supporting wall that's been fettled with?

The interesting thing is the pier only needs to be rebuilt from the cill to the lintel level. I would have through that the blocks directly under the cill level would have been under 57kN force, but he seems quite happy that the force dissipates through the wall under the window.

Corbelling effect.
If you imagine pulling a lintel out of a wall, e.g. from over a door, the wall doesn't collapse vertically above all the way to the top of the building. It's just a triangle of bricks over the door which fall out. The rest are supported by transfering their weight to the wall either side of the door.
