Plumbing Up Steel Columns

Plumbing Up Steel Columns

Plumbing Up Steel Columns

(OP)
I am a setting out engineer and am being pushed more towards construction aspect of engineering at work(used to be civils) and was looking for advice on the best/easiest way to plumb up steel columns prior to grouting.I Am ok with aligning them onto grid.  
 

RE: Plumbing Up Steel Columns

Do you mean physically, as in using the leveler nuts hopefully installed under the base plates? Or do you  mean how do you go about setting up a transit/laser etc to get your columns plumbed and aligned prior to erecting your horizontal steel?

RE: Plumbing Up Steel Columns

Careful.  He might be running small vertical piping drain lines down the sides of his columns.  8<)   

(I'm going to listen to the experts on this one - my work usually starts after the columns are in place, or in "perfectly vertical" artificially-correct 3D CAD columns.)    

Real world?  Haven't done much of that in placement of building columns.    

RE: Plumbing Up Steel Columns

Are you talking about single storey of multi-storey.

If single storey of 3-5m I would start by setting them on shims to the correct alignment at the base plates and then using a spirit level (a long one that has been checked for accuracy). I would then carry out a further check with a theodolite.

If multi-storey then it is more complicated and the spirit level wouldn't achieve much especially between floors. In my days as a setting out engineer I would have used a theodolite, but I hear that vertical plumbing lazers are now in common use.

Thanks for replys guys forgot to mention I would be checking columns after they had been shimmed and aligned onto grid by erectors and would be using total station to line in afterwards so i was wondering og the best way to plumb them up ie do i sight the top then measure the difference at the bottom (if any) with a tape measure.
