A site plan (figure 2-8) shows the contours, boundaries, roads, utilities, trees, structures, and any other significant physical features on or near the constructionsite. The locations of proposed structures are shown in outline. This plan shows comer locations with reference to reference lines shown on the plot that can be located at the site. By showing both existing and finished contours, the site plan furnishes essential data for the graders.
The plot plan shows the survey marks with the elevations and the grading requirements. The plot plan is used by the Engineering Aids to set up the corners and perimeter of the building using batter boards and line stakes, as shown in figure 2-9. Thus, the plot plan furnishes the essential data for laying out the building.
