QA vs QC is one of the most confused topics in construction and architecture, and the ARE and CDT love to test it. This episode breaks down the difference: quality assurance prevents problems, quality control catches them.
You'll learn how QA and QC work across design, construction documents, and construction administration, who is responsible for what between the architect, owner, and contractor, and how a QA/QC plan fits into project delivery. Emily walks through everyday analogies and a full curtain wall example so the concepts actually stick.
Whether you're studying for the ARE, working toward your CDT, or already in practice, understanding QA/QC will make you a sharper architect and help you on exam day.
