Column Numbering System
Column Numbering System
(OP)
Can anyone direct me to a published standard for column numbering within a factory? Any help would be much appreciated.
Thanks
Thanks

RE: Column Numbering System
Usually columns are laid out in a grid and one axis is lettered and the other is numbered thus column B5 is at the intersection of lines ‘B’ and ‘5’. This often works well for construction, especially if the grid lines are evenly spaced.
I have also seen industrial plants laid out in a coordinate system. There is an x-y numbering system for everything in the plant. Thus you would see say anchor bolts or column centre lines designated something like (123.456, 987.654). (Elevation can also be included for a 3-d descriptor)
This works well as long as everything is laid out along the grid lines however this is not always the case. I have seen coordinates laid out for the project and then translated into the master coordinate system later. This can be confusing and error prone. (Is the coordinate a job or a master coordinate? Was the arithmetic correctly done and all numbers transcribed correctly.)
Can you tell us why you are asking? Are you setting up a system and just want to be to some industry standard or did your pointy haired boss tell you to use a published standard not knowing that one does not exist?

Also, it is very handy to prepare a good key plan, showing all the grids for the facility. This can even be a separate sheet and may only contain grids, exterior walls, bearing walls, etc.
Also, horizontal and vertical control tied into the existing building is important (This is a real headache with some hospitals).
