In a construction drawing, what does a plot indicate?

The correct choice highlights that a plot on a construction drawing indicates the location of manmade features. In construction drawings, plots are typically used to represent various structures, such as buildings, roads, and other infrastructure. This information is crucial for understanding how these features fit together within the site and how they relate to each other spatially.

Manmade features are essential components of civil engineering and architecture, as they inform builders and planners about the design layout, access points, utility placements, and aesthetic arrangements. By visualizing these features on a plot, stakeholders can assess if the project meets zoning regulations and spatial requirements.

In contrast, while the other options mention important elements in construction and site analysis, they do not specifically define what a plot signifies within a construction drawing context. Utilities are depicted separately, surface area calculations can be derived from various parts of a drawing, and soil type information is usually presented through geological surveys or soil maps. Thus, the representation of manmade features is the best fit for what a plot indicates in this scenario.
