Who is responsible for both QA and QC?

• A. The Owner
• B. The Design-Builder
• C. The Architect
• D. The Construction Manager

Answer: (B)

In a design-build project, the party responsible for both QA (Quality Assurance) and QC (Quality Control) is the Design-Builder. This arrangement places a single entity in charge of the entire quality program, spanning both design and construction. QA involves the planned processes and systems put in place to prevent defects and ensure the project will meet all requirements, while QC is the verification step that checks and tests outputs to confirm they conform to those requirements. Because the Design-Builder controls the design and the construction execution under one contract, they can develop and implement the QA plan, conduct design reviews, approve materials, and schedule testing and inspections, then perform or arrange the QC activities to verify compliance and address any defects. This integrated approach reduces gaps and misalignments that can occur when quality responsibility is divided among separate parties. The Owner can specify performance criteria and participate through oversight, but the overall QA/QC program is owned and managed by the Design-Builder. The Architect and Construction Manager may contribute to reviews or on-site oversight, but they do not bear the primary, overarching responsibility for the integrated QA and QC program.
