standard drawing sheet size, while a residential backyard having dimensions of 75 by 120 feet could be drawn at 10 or 20 scale. In the case of the golf course, two sets of drawing scales might be used: an overall general plan layout of the course at 100 scale with a minimum of detail, then several drawings representing portions of the golf course drawn at 20 or 40 scale so that required detail and accuracy are possible. Individual greens that require considerably more detailed grading information might be drawn at 10 or 20 scale. When a project—such as a golf course—is subdivided into a number of plans, a referencing system is required to ensure that the information of one plan can be seen in relation to adjacent portions of the project. The decision as to which scale should be used when preparing to draw a plan or detail considers several factors: the size of the project area, the complexity of the designed elements, and the level of detail required to communicate the design intent to contractors. At an early phase of the design process—when drawings are made to inform the client and gain approval to proceed in the design development and contract document phases—a scale might be different than the ones used in subsequent work phases. As a general practice, an attempt is made for all the major plan drawings to be drawn at the same scale. This depends on the areal size of the project site and the level of design detail required. The drawings might include: site demolition, grading, staking and layout, planting, irrigation, lighting, and other construction components.
Reference Plan and Match Lines The reference plan showing the project subdivided into individual smaller areas is shown in Figure 5.2. The reference plan might be drawn at 50 or 100 scale, with the individual subplans drawn at 20, 30, or 40 scale. Notice the darker lines outlining each sheet beginning with L3–01 thru L3–14. The dark lines “match lines” that are used to make the locational relation between each individual sheet visually apparent. Each subsheet from the reference plan is contained within the system
