What is a "combination drawing" used for?

A "combination drawing" is specifically used to integrate both structural and placement details into a single representation. This type of drawing serves as a comprehensive reference that allows inspectors and engineers to understand how various structural elements fit together, as well as how they should be positioned during construction. By combining these two aspects, it enhances clarity in communication among all stakeholders involved in the project, from design to execution.

While creating blueprints for future reference, enhancing visual presentation, and analyzing design efficiency are important aspects of design and engineering, they do not capture the primary function of a combination drawing. These other functions may involve different types of drawings or documentation that focus more on the conceptual, visual, or analytical elements rather than the combined structural and placement specifics that a combination drawing provides.
