Information needed to determine the radius.
What is the rise and span?
The most important approach to keeping records on the job.
What is the daily job log?
A part of the circumference of a circle.
What is an arc?
In order to bisect a line you must use this dimension.
What is greater than half the span?
The point from which the arc is swung.
What is the strike point?
Used to document the time, materials, and equipment used on work performed outside of or in addition to the original contract documents.
What is an EWO, Extra work order, TAG?
The line between the two ends of the arc, perpendicular to the centerline.

What is Graphing the Arch?
Formula to find the radius of an arc.
What is
Radius = ((1/2 span)^2 div Rise + Rise)/2
Clarify missing or inconsistent information from the prints.
What is an RFI?
The name for the distance across the arch.
What is the span?
You need these two dimensions to graph an arch.
What is the rise and the span?
Formula to find the rise of an arch.
Rise = Radius - sqrt radius^2 - (span^2)/4
Don't order these until your change order has been approved.
What is materials?
Shows the sequence of each activity, the start of each activity, the dependence of that activity on the completion of a preceding activity, and how the completion of that activity will restrict the commencement of subsequent activities.
