What is the main focus of the Basis of Design Documents?

The Basis of Design Documents primarily serve to outline how the project design meets the client's needs and requirements, establishing a framework as to the rationale behind the design choices made. One critical aspect is the documentation of design assumptions and the criteria that influence those assumptions. This includes the order of preference in design changes, which assists in maintaining a clear priority for modifications and ensuring consistency in embracing client objectives while managing adjustments efficiently.

This focus helps all stakeholders — including designers, contractors, and owners — understand the essential foundation of the project’s design. It acts as a reference point for guiding future design decisions and helps in communicating the intent behind design elements, thus promoting coherence throughout the project's lifecycle.
