I very much appreciate the help... If this proves to work it will save me mucho time, effort and stress manually plumbing up lines from the existing slab below.
Love that pathagoras too by the way, I don't know how buildings would be constructed square and now apparently round without him!

image not uploading well or I'm diong it wrong. Let me explain better...
I have a circle with a radius of 108m.
I have points along the perimeter of this circle which have a chord length of 9144mm.
what i want to do is, every say 500 mm along this chord, turn 90 degrees and plot a point along the arc.
I dont know how to find the distance from this cord at these particular points.
Does this clarify the problem any?

I am working in construction and laying out a radius wall for a hospital that we are building. I have to provide several points along this radius for the formwork to be built. I know the raduis of the wall (108m), I know the distance between columns [(represented by 'b' in the image provided)9.114m]. Now what I want to do is create a value for 'a' and find 'c' from that.
I'm hoping I have explained concisely enough 
I am also hoping there is a simple formula that I can use to figure this out. Any help will, needless to say, be appreciated!
