What is the purpose of additional drawing types in construction documentation?

The purpose of additional drawing types in construction documentation is primarily to supply required construction information. These drawings are crucial for conveying detailed instructions and specifications that go beyond what typical plans may show. They often include various specifics, such as dimensions, materials, components, systems, and methods of construction, ensuring that all parties involved—architects, engineers, contractors, and subcontractors—have a clear understanding of the project's requirements.

While aesthetics can play a role in the overall presentation of a project, and communication is indeed important among stakeholders, additional drawing types serve a foundational role in providing the essential technical information needed for construction. Similarly, documenting costs is a separate consideration that aligns more with financial management rather than the primary function of construction drawings. Thus, the primary focus of these additional drawing types is to deliver the essential details necessary for effective and accurate construction.
