Foundation Layout Nomenclature

[Toivul]

Hopefully this is an easy one. Can anyone tell me what W1+70'-6" means on a layout drawing? I'm assuming it means 70 feet 6 inches west of some reference point. Is my thinking correct?

Thanks

So it would seem, but ASK the author/designer. There are a whole hell of a lot of ways to lay out a drawing, and you're asking a very multi-national crowd. I doubt you'll get the right answer here without posting much more info, and at minimum:

- What country/code/geographic area of practice.
- Age of drawing.
- Purpose of set-out.

Thanks for the reply I will remember to add more information next time.

For anyone interested: In North America for process piping, the first letter is the direction from the "bench mark" (reference point) on the drawing, i.e. N would be North, S would be South, etc. The first digit after the letter is the number of hundreds of feet from the bench mark, i.e. 1 is 100', 2 is 200', etc. So N1+70' - 6" would be 170 feet 6 inches North of the bench mark on the drawing.

Might be West 170'6"...
