standard drawing sheet size, while a residential backyard having dimen-
sions 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. Indi-
vidual greens that require considerably more detailed grading informa-
tion 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 rela-
tion 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.
