In which contract type is the standard of care threshold most commonly applied in practice management?

• A. Design-bid-build
• B. Design-build
• C. Integrated project delivery
• D. Construction management at risk

Answer: (A)

Standard of care describes the level of professional competence and diligence expected from design professionals, defined by accepted industry practices and the contract obligations they assume. This concept is most clearly applied in the traditional design-bid-build model, where design and construction are handled by separate entities under distinct contracts. In this setup, the designer’s responsibility to meet professional standards is a direct, contractually identifiable duty, making it straightforward to evaluate whether the design work meets the expected level of care.

In other contract forms, like design-build, IPD, or CMAR, design and construction responsibilities are more integrated or shared among participants. That integration shifts how risk and performance are assessed, often blending design quality with construction performance and reducing the clarity of a single, discrete standard-of-care threshold. That’s why the traditional design-bid-build arrangement is where the standard of care is most commonly applied in practice management.
