PLOT PLANS. - A plot plan (also called a site plan) includes not only the project but also the surrounding area. The project may be represented only by an outline, such as the Director's Quarters project on the plot plan in figure 2-7. The grades at fixed points are shown throughout the area. This is done to show how the land slopes before construction is started and the finished grade after construction is completed. The north arrow symbol, used for orientation of the drawing, is shown. The Construction Electrician may have to have a plot plan to construct a pole line to the project site at or near the earliest phase of construction. Another example is when the slope and grade of the surrounding area is to be changed and you have to bury cable or conduit. You must know what the finished grade is and how deep to dig. This type of work requires close coordination between you, the Engineering Aids, Equipment Operators, and Builders. By looking over the plot plan, you will know what to do to prepare for the job.
