Yep, sorry you're quite right it's kN. I could give excuses about it being a typo, but looks like I've written it twice. I could use the excuse that I don't know what Nm are, but I own a couple of torque wrenches. I could use the excuse that it was late, but the post was at
20:52. So I'll quit while I'm behind :DThe 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.
