In DB, requirements are _____ based.

• A. Cost
• B. Time
• C. Performance
• D. Safety

Answer: (C)

In design-build, requirements are stated in terms of performance. That means the owner specifies what the project must achieve—the outcomes, functions, reliability, safety, energy performance, operability, maintenance needs, and other measurable results—without prescribing exactly how to build it. The design-build team then develops a solution that meets those performance targets, allowing flexibility in design and construction methods to optimize cost and schedule while still delivering the required results. Cost and time are important project constraints that influence how the performance targets are met, but they don’t define the requirements themselves. Safety is essential and is reflected in the performance criteria as part of the desired outcomes, rather than being the sole basis of the requirements.
