The various drawings that may be prepared are the following:
• Layout plan
• Grading plan
• Planting plan
• Construction details
Layout Plan
The layout plan gives the horizontal dimensions of all the proposed design elements and areas of the design (Figure 4-9). Typically, a contractor is selected in this situation through a bidding process. But where there is extensive proposed construction (decks, steps, walls, fences, trellises, and so on), planting, or regrading of the site, construction drawings are essential to ensure that the design is implemented to the level of quality desired by the designer. For nonpaved areas such as lawns and planting beds, this is best shown with contour lines. The plant list normally indicates the quantity, size, condition, and other important notes about each of the specified plants. These drawings are referred to as construction drawings because they illustrate and explain to the contractor how to implement the design. This type of bidding process lets the homeowner compare prices among contractors before selecting the one to do the work. As the name suggests, construction details are drawn to communicate how specific portions of the design are to be built. Need for Construction Drawings
The layout, grading, and planting plans along with the construction details should all be drawn in coordination with one another. O’ &’ 10′ 2O’

Master plan. It does not get directly involved with implementing a project. When this is possible, construction drawings may be very simple or even unnecessary to communicate how the design is to be implemented. For paved areas, proposed elevations are often communicated through the use of spot elevations (Figure 4-10). Whether or not these drawings are prepared for a particular project depends on the complexity and budget of the project. Sometimes several sheets or more of construction details are prepared to adequately explain how to build all the various parts of a project. The dimensions should be given in reference to fixed elements such as a property line or a side of the house. And there is apt to be much more supervision of the implementation by the designer in a design/build firm. Construction Details
Construction details often accompany the layout, grading, and planting plans. That is, the construction drawings are “let out for bid” by having a selected number of contractors submit price quotations for the implementation of the design. NEWELL RESIDENCE

Preliminary plan. A plant list that identifies the genus and species of all plants in the design should accompany the planting plan. When completed, these drawings inform the contractor(s) how the design is to be implemented. The type of company will also determine whether or not construction drawings are used.
