Once the master plan has been completed and accepted by the clients, it may be necessary to prepare other drawings in order to sufficiently implement the design as expressed in the master plan. These drawings are referred to as construction drawings because they illustrate and explain to the contractor how to implement the design. The various drawings that may be prepared are the following:
• Layout plan
• Grading plan
• Planting plan
• Construction details
The layout plan gives the horizontal dimensions of all the proposed design elements and areas of the design (Figure 4-9). The dimensions should be given in reference to fixed elements such as a property line or a side of the house.
The grading plan identifies the existing and proposed elevations of the ground plane. For nonpaved areas such as lawns and planting beds, this is best shown with contour lines. For paved areas, proposed elevations are often communicated through the use of spot elevations (Figure 4-10).
