What type of drawings are referred to as "C" drawings?

"C" drawings refer to civil drawings, which are primarily focused on the design and detailing of infrastructure and site layouts. These drawings include site plans, grading plans, and utility plans, which outline the general arrangement of structures, roads, and other elements necessary for site development.

Civil drawings are essential in ensuring that the construction meets regulatory standards and integrates properly with the surrounding environment. They provide critical data about existing features, such as topography and drainage, and indicate where utilities like water, sewer, and electrical systems are to be installed.

In contrast, architectural drawings primarily focus on the design of buildings and their layouts. Structural drawings detail the framework and support system of a construction project, while electrical drawings illustrate the wiring and electrical systems. Each type serves its own purpose and follows specific conventions, but "C" drawings are distinctly known for their civil engineering applications.
