1-2. Working Drawings. Working drawings and specifications are the
main sources of information for supervisors and technicians
responsible for the actual construction. The construction working
drawing gives a complete graphic description of the structure to be
erected and the construction method to be followed. A set of working
consist of plans and elevations; detail drawings consist of sections
and detail views.
a. Site Plan. A site plan (also called a plot plan) (Figure 15)
shows the boundaries of the construction site, the location of the
building in relation to the boundaries, the ground contour, and the
roads and walks. It may also show utility lines such as sewer, gas,
and water. This type of plan is drawn from a survey of the area by
locating the corners of the building at specific distances from the
established reference points.
