Which type of study is included as an additional service under RAIC Doc 6?

The inclusion of business case development as an additional service under RAIC Doc 6 reflects the architectural profession's expanding role in providing comprehensive services to clients. Business case development involves creating a structured proposal that outlines the justification for a project, including its financial aspects and strategic alignment with client goals. This service is integral for clients as it helps them assess the viability and potential return on investment for architectural projects.

Feasibility studies on market trends, while valuable, typically fall into broader assessments rather than tightly integrated architectural services. Structural engineering analysis and interior design consultation are usually considered standard architectural services and are not categorized as additional services in the same way that business case development is, focusing instead on the requisite technical aspects of a project rather than its strategic or financial justifications.
