Setting Out

There are several methods available for establishing the location of points along the centreline of the engineering curve. Some of these are rarely used these days, the system is generally dominated by the use of coordinates as the method of computation, so the use of radiations from control points is common. In any case, all pegs and marks placed must be checked, and the preferred method for that is to use a different method to check from that used to peg.
